1、
#include <stdio.h>
int main(void)
{
int i;
puts("please input an integer.");
printf("i = "); scanf("%d", &i);
while (i > 0)
{
printf("hello world!\n");
i = i - 1;
}
printf("\n");
return 0;
}
↓
#include <stdio.h>
int main(void)
{
int i;
puts("please input an integer.");
printf("i = "); scanf("%d", &i);
while ( i-- > 0)
{
printf("hello world.\n");
}
return 0;
}
