Defendants assign as error the overruling by the court of their objection to an in-court identification of the defendants by the prosecuting witness Fisher.
When Fisher was asked to make an in-court identification of the three defendants, objections were interposed on the grounds that such identification would be tainted by the out-of-court identifications made of McPherson and Jones from photographs and made of Harris from the confrontation at the police station. Defendants contended the photographic technique used in this case was too suggestive in that the prosecuting witness was tendered only six or seven photographs from which he selected two as being pictures of two of his assailants. They contended that the prosecuting witness’ identification of defendant Harris at the police station was illegal in that he was permitted by the police to “walk up” on Harris and identify him while Harris was in custody of the police and not represented by counsel.
Before overruling defendants’ objection to the in-court identification a voir dire examination of the prosecuting witness was ordered. His testimony on voir dire indicated that he had a good and sufficient opportunity to observe defendants as they stood approximately five feet from him in front of the store for a period of about 3 minutes; that he observed them further as they walked slowly past him to the street corner and that he got a good look at all of their faces while they were robbing him. He also testified that shortly after he was robbed he gave a description of his assailants to the police as to their relative size, hair style, age, complexion, and style and color of the clothes they were wearing. The witness stated that he clearly recognized the three men in the courtroom as the men, he was with on Fayetteville Street the night of the robbery. The court made appropriate findings of fact based on the voir dire evidence and concluded that the witness’ identification of each defendant was based upon his observation of them on the night of the alleged attack and was not tainted by any illegal procedures.
*164 The question of the legality of the identification of two defendants through the use of photographs and the third through the police station confrontation is before us for consideration only if the court erred in finding that the in-court identification was not affected by such procedures. Such finding must be based on clear and convincing evidence. United States v. Wade, 388 U.S. 218, 87 S.Ct. 1926, 18 L.Ed. 2d 1149; State v. Stamey, 3 N.C. App. 200, 164 S.E. 2d 547. Where the evidence, as here, shows that the witness had a good and sufficient opportunity to observe a defendant at the time the offense was being committed, and testifies that his in-court identification is based on his observation made at that time, the test of “clear and convincing evidence” is met and will support findings such as were made by the court in this case. State v. Stamey, 6 N.C. App. 517, 170 S.E. 2d 497. See also State v. Gatling, 275 N.C. 625, 170 S.E. 2d 593; State v. Primes, 275 N.C. 61, 165 S.E. 2d 225; State v. Williams, 274 N.C. 328, 163 S.E. 2d 353. The evidence here supported the court’s findings, which are binding on appeal. This assignment of error is overruled.
Defendants further contend that the court committed error in overruling their motion for mistrial based on comments made by the court in the presence of the jury.
The prosecuting witness testified on both direct and cross-examination that the defendant Harris at the time of the robbery was wearing “pea green or light blue colored clothes.” While counsel for the defendant Harris was questioning this witness further on cross-examination, the following exchange took place:
“Q. Do you know how to make green?
A. Do I know —
OBJECTION BY THE STATE
THE COURT: Mr. Brogden, do you know how to make all these colors?
MR. BROGDEN: Yes sir, they teach you in grammar school. I got one eight years old can tell you.
THE COURT: Do you know how to make it?
MR. BROGDEN: Yes sir.
THE COURT: Why don’t you go in the paint business. Let’s don’t get meticulous with all the colors in the world.
MR. BROGDEN: Make a motion for a mistrial.
THE COURT: Motion is denied. Have your seat and continue your cross-examination.”
*165We have held that exchanges such as this between counsel and the court should not be engaged in before the jury. State v. Cox, 6 N.C. App. 18, 169 S.E. 2d 134. Every person charged with a crime has an absolute right to a fair trial before an impartial judge and an unprejudiced jury in an atmosphere of judicial calm. State v. Belk, 268 N.C. 320, 150 S.E. 2d 481. Unflattering exchanges between court and counsel are not conducive to the decorum that should prevail in a courtroom during a trial. However, when determining whether such comments or remarks are sufficiently prejudicial to require a new trial the test applied is their probable effect upon the jury and the utterances must be considered in the light of the circumstances under which they were made. State v. Carter, 233 N.C. 581, 65 S.E. 2d 9. We cannot say under the circumstances here that the colloquy between the court and counsel for defendant Harris prejudiced the jury against the defendants. It was prompted by counsel’s question on cross-examination as to whether the prosecuting witness knew how to make green color. This was after the witness had been cross-examined at length concerning his ability to identify colors by looking at various objects including clothing worn by some of the jurors. Whether the witness could make green color was irrelevant to his ability to see and distinguish between colors. The court’s impatience with this line of questioning, and not its opinion, is demonstrated by the exchange. In our opinion no prejudice resulted to defendants. State v. Cox, supra.
Defendants further assign as error the sustaining by the court of its own objection to the following line of questioning:
“Q. You had three dollars worth of change?
A. Yes sir.
Q. What you doing carrying three dollars worth of change around?
THE COURT: Objection sustained.
MR. BROGDEN: I want the jury excused and put his answer in the record had he been allowed to answer the question.
THE COURT: Motion denied. ALL DEFENDANTS EXCEPTS. (sic) EXCEPTION # 14B
MR. BROGDEN: We will have to get it in the record.
THE COURT: Motion denied to put it in the record. Everything we have said is in the record.”
In the exercise of its right to control and regulate the conduct *166of the trial, a court may on its own motion exclude or strike evidence which is wholly incompetent or inadmissible. Greer v. Whittington, 251 N.C. 630, 111 S.E. 2d 912. Defendants have not shown that the questions concerning the varied change and dollar bills Fisher had when he was robbed were relevant or material. It was incumbent upon them to do so in order to show prejudice. Greer v. Whittington, supra; Johnson v. Heath, 240 N.C. 255, 81 S.E. 2d 657.
Defendants complain also that they were not permitted to put in the record what the witness’ answer would have been. For an exception to the exclusion of testimony to be sustained on appeal, the record must show what the testimony would have been if the witness had been permitted to answer. State v. Poolos, 241 N.C. 382, 85 S.E. 2d 342; State v. Phillips, 5 N.C. App. 353, 168 S.E. 2d 704. It is incumbent upon the proponent’s counsel to request that the answer be given to the court reporter, and once the request is made, it is the duty of the court to see that it is done. Here, however, the question itself was irrelevant and it has not been made to appear how the answer, whatever it may have been, would have benefited defendants. Under such circumstances the failure of the court to permit the witness to answer for the record was not prejudicial error warranting a new trial.
Other assignments of error made by defendants have been considered and found without merit. All three defendants were represented by competent counsel and their rights were vigorously protected throughout the trial. We have reviewed the entire record and find no error of such a prejudicial nature as to warrant a new trial.
No error.
