222 S.E.2d 718 (1976)
STATE of North Carolina
v.
Clayton Allen MARTIN alias Manuel Clay.
No. 7519SC835.
Court of Appeals of North Carolina.
March 17, 1976.
*719 Atty. Gen. Rufus L. Edmisten, by Special Deputy Atty. Gen. John R. B. Matthis, Raleigh, for the State.
Robert M. Critz, Kannapolis, for defendant-appellant.
MORRIS, Judge.
Defendant, noting that the bill of indictment only referred to the alleged armed robbery of Clyde Adams, Jr., contends that the trial court erred in charging the jury that defendant would be accountable for the crime charged if they, inter alia, found beyond a reasonable doubt that defendant robbed "Mr. Adams or Mrs. Plott". Defendant argues that this variance ". . is an inaccurate and misleading mandate on armed robbery". We disagree. This variance, if any, works no prejudice to the defendant and raises no constitutional claim of potential double jeopardy.
In State v. Harris, 8 N.C.App. 653, 657, 175 S.E.2d 334, 336 (1970), our Court stated that "`[t]he purpose of the rule as to variance is to avoid surprise and to protect accused from another prosecution for the same offense. . . .'" (Citation omitted.) Here the evidence indicates that defendant, by the use or threatened use of a firearm, robbed various Big Star employees *720 of company monies and did not rob Mrs. Plott of any of her personal property. Therefore, we have before us but one, single criminal transaction and the defendant is in no danger of a subsequent prosecution for the armed robbery of Mrs. Plott. This variance, therefore, worked no prejudice to defendant, and the charge did not confuse the jurors as to the charge for which defendant was being tried; namely, armed robbery of a food store's cash receipts. See: State v. Potter, 285 N.C. 238, 204 S.E.2d 649 (1974); State v. Ballard, 280 N.C. 479, 186 S.E.2d 372 (1972); State v. Holland, 20 N.C.App. 235, 201 S.E.2d 85 (1973), cert. denied 284 N.C. 619, 202 S.E.2d 275 (1974). Cf: State v. Johnson, 23 N.C. App. 52, 208 S.E.2d 206 (1974), cert. denied 286 N.C. 339, 211 S.E.2d 215 (1974).
Defendant next maintains that the trial court erred in failing to charge on the lesser included offense of common law robbery. We find no merit in this contention. Here all the evidence supports the instruction on armed robbery, and there is no evidence that defendant engaged in an offense tantamount to common law robbery. "If the State's evidence shows an armed robbery as charged in the indictment and there is no conflicting evidence relating to the elements of the crime charged an instruction on common law robbery is not required." State v. Lee, 282 N.C. 566, 569-570, 193 S.E.2d 705, 707 (1973); State v. Segarra, 26 N.C.App. 399, 216 S.E.2d 399 (1975), cert. denied 288 N.C. 395, 218 S.E.2d 469 (1975).
Defendant also contends that the trial court erred in permitting witness Mike Stevens to identify the defendant prior to conducting a voir dire examination as to the admissibility of the witness's in-court identification after defendant interposed an objection. We overrule this contention. The trial court did allow a subsequent voir dire examination and determined that the identification was admissible. Moreover, Mike Stevens's identification of defendant merely corroborated previous in-court identifications offered by several other witnesses. While it would have been better procedure for the court to have conducted a voir dire upon defendant's first objection, we nevertheless deem it to be harmless in view of the total circumstances of this case.
We have considered defendant's other contentions and find them also to be without merit.
No error.
VAUGHN and CLARK, JJ., concur.
