#include <stdio.h>

int sort(int numArray[], int counter);
int main(void)
{
    int numArray[100];
    int counter = 0;
    int i = 0;
    int x;

    while (i < counter && y != 0)
    { //improvement 2   
        sort(numArray, counter - i); //improvement1
        i++;

    i = 0;
    while (i < counter)
    {
        printf("%d", numArray[i]);

int sort(int numArray[], int counter);
int num = 0;
int i;
int x;

for(i = 0; i < counter-1; i++)
{
    if (numArray[i] > numArray[i+1])
    {
        x=numArray[i];
        numArray[i]=numArray[i+1];
        numArray[i+1]=x;
        num++;
    }
}

return num;

你的for循环不在任何函数之内。我猜你的意思是将int num = 0到return num内的所有内容都放在sort函数中。你需要将函数体包装在花括号{和}中，如下所示：

int sort(int numArray[], int counter)
{
    int num = 0;
    int i;
    int x;

    for(i = 0; i < counter-1; i++)
    {
        if (numArray[i] > numArray[i+1])
        {
            x=numArray[i];
            numArray[i]=numArray[i+1];
            numArray[i+1]=x;
            num++;
        }
    }

    return num;
}
