C语言将For循环改为While循环 [英] C language Changing For Loop to While loop

问题描述

如何将for循环变成while循环
是否可以将array中的for循环改为while循环?

How to make for loop to while loop
Is it possible to change for loop in array to while loop?

改变

for(i = 0; i < 12; ++i) //for loop for selecting only positive
    {
        if(a[i] > 0) printf("%d ", a[i]); //display positive only using if statement
    }

to

int i = 0, a[12];
    while(i < 12)
    {
        if(a[i] > 0)
        {
            printf("%d ", a[i]);
        }
        i++;
    }

但如果更改，它不会显示与负数相同的正数..

but it doesn't display the positive same as the negative if changed..

推荐答案

int i;
for(i=0; i < count; i++)
{
    // Work item here
}

在功能上等同于

int i=0;
while (i < count)
{
    // Work item here
    i++;
}
