程序代码：

#include <stdio.h>
int main(int argc, char* argv[])
{
    char a[10] = {0};
    char c;
    char *p = a;
    scanf("%s",a);
    getchar();
    scanf("%c",&c);
    while(*p)
    {
        if(*p == c)
        {
            printf("%d\n",p-a+1);
            break;
        }
        p++;
    }
    return 0;
}
