c - 当字符串匹配时循环不会终止

Question

这个问题已经有答案了:

How do I properly compare strings in C? (10 个回答)

已关闭 4 年前。

循环不起作用，请提供任何答案，未使用某些变量..我知道，但它不会跳出循环

#include <stdio.h>
#include <stdlib.h>



int main(){

    char name;
    int Employees=0, idnum;
    float Low=99999, High=0, earnings, Tearnings=0, Avgearnings;


    while(name != "xxxx"){


        if(earnings < Low)
        {
            Low = earnings;
        }


        if (earnings > High)
        {
            High = earnings;

        }


    printf("Enter name\n"); 
    scanf("%s", &name);

    printf("Enter earnings\n"); 
    scanf("%f", &earnings);


    Tearnings = Tearnings / earnings;
    Employees = Employees ++;

    }


    Avgearnings = Tearnings / Employees;

    printf("Average earnings: %2f", Avgearnings);
    printf("Lowest Earnings: %2f", Low);
    printf("Highest earnings: %2f", High);


    return 0;   
}

不会退出循环

Answer 1

您正在使用 while 循环，没有任何真正的中断条件。

您应该添加 if (xxx) {break}或者将其更改为 var i;
for (i=0, i < earnings.length ; i++) { ... }通过这样做，它应该让计划流程涵盖所有员工/收入，并在到达最后一个后继续。
