编程学习网为您整理以下代码实例，主要实现：内部块与外部块中的变量名称相同时覆盖，希望可以帮到各位朋友。
#include <stdio.h>
int main(){
int x = 30; // original x
printf("x in outer block: %d at %p\n", x, &x);
{
int x = 77; // new x, hIDes first x
printf("x in inner block: %d at %p\n", x, &x);
}
printf("x in outer block: %d at %p\n", x, &x);
while (x++ < 33) // original x
{
int x = 100; // new x, hIDes first x
x++;
printf("x in while loop: %d at %p\n", x, &x);
}
printf("x in outer block: %d at %p\n", x, &x);
return 0;
}
