C语言开发示例：29. 使用calloc分配内存

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

int main()
{
    int *pNumber = (int *)calloc(25, sizeof(int));
    if (!pNumber)
    {
        printf("failed to malloc");
        return -1;
    }
    for (int i = 0; i < 25; i++)
    {
        *(pNumber + i) = i;
    }
    for (int i = 0; i < 25; i++)
    {
        printf("%d\n", *(pNumber + i));
    }
    free(pNumber);
    pNumber = NULL;
}
