萌新求助，大佬赐教哈，还想让这个程序可以循环怎么弄啊，自己学的不会......

//if(x=+)
if(x=='+')

#include <stdio.h>
main()
{
    int a,b,c;
    char x;
    scanf("%d %c %d",&a,&x,&b);
    if (x=='+') c=a+b;
    else if (x=='-') c=a-b;
    else if (x=='*') c=a*b;
    else if (x=='/') c=a/b;
    else return;
    printf("The Result is %d\n",c);
