C语言关于输入输出的printf函数的类型完全相同，但是为什么我看不到输出？

Question

#include<stdio.h>

int main(void)
{

    char name[40];      
    scanf("%s",name);

   if(name == "yes")    
   {
       printf("%s",name);
   }

   return 0
}

Answer 1

您需要使用strcmp进行字符串比较。

替换

if(name == "yes")

与

if(strcmp(name,"yes") == 0)

strcmp 返回

1. 0 if both strings are identical (equal)

2. Negative value if the ASCII value of first unmatched character is less than second.

3. Positive value if the ASCII value of first unmatched character is greater than second.
