当用户输入数字时，计数值并再次返回到代码的开头

Question

程序计算出输入的内容后，会打印出该值，然后程序会询问是否继续，如果我按“Y”，程序将从用户输入数字时的开头开始。问题是如果用户按“Y”如何使程序回到开头？

#include <stdio.h>
#include <stdlib.h>
void VOne();
int main(void) {
  VOne();
  return 0;
}

void VOne() {
  int i,quiz,exer,test,Final,FV,back;
  char again;
  while (1) {

    printf("Input Value : ");
    scanf("%d %d %d %d",&quiz,&exer,&test,&Final );
    FV = 0.10+(0.10*quiz)+(0.15*exer)+(0.30*test)+(0.35*Final);
    printf("%d\n",FV );
    if (FV >= 75) {
      printf("You pass the this class\n" );
    }
    else {
      printf("You've to take this class again in the next term\n");
    }
    printf("You want to input again?\n'Y'or'N\n");
    scanf("%c ",&again );
    if (again == 'y') {
      continue;
    }
  }
  return;
}

Answer 1

这应该有效。

#include <stdio.h>
#include <stdlib.h>
void VOne();
int main(void) {
  VOne();
  return 0;
}

void VOne() {
  int i,quiz,exer,test,Final,FV,back;
  char again;
  while (1) {

    printf("Input Value : ");
    scanf("%d %d %d %d",&quiz,&exer,&test,&Final );
    FV = 0.10+(0.10*quiz)+(0.15*exer)+(0.30*test)+(0.35*Final);
    printf("%d\n",FV );
    if (FV >= 75) {
      printf("You pass the this class\n" );
    }
    else {
      printf("You've to take this class again in the next term\n");
    }
    printf("You want to input again?\n'Y'or'N\n");
    scanf(" %c ",&again );
    if (again == 'y' || again == 'Y') {
      continue;
    }
    else break;
  }
  return;
}
