与if语句中的字符串比较不起作用 [英] Compare with string in if statement doesn't work

问题描述

我尝试比较从scanf和fscanf获得的两个字符串。我已经弄明白每个变量里面的内容是什么。它都显示相同的字符串，但在if语句中与这两个字符串进行比较后，它不起作用并执行else语句。我的代码出了什么问题？

I try to compare my two strings that obtained from my scanf and fscanf. I already figured out what is the content inside the each variable. It both show the same strings, but after I compare with this two string in if statement, it doesn't work and execute else statement instead. What's wrong with my codes ?

int main(void)
{
...
char input[256];
printf("Enter your name: ");
scanf("%s",&input);

fp = fopen(_FILE,"r+");
for(i=0;i<textlines(_FILE);i++)
{
 fscanf(fp,"%s %d",stuff[i].name,&stuff[i].salary);
 if(input == stuff[i].name)
 {
 // Update name here
 }
 else
 {
 printf("Not Found");
 }
}
return 0;
}

推荐答案

== just checks for pointer equality. Use strcmp instead
