源代碼：

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

#define SIZE  10

int main(char argc, char *argv[] )
{

    int *p = NULL, *tmp;

    int i;
    p=(int*)malloc(sizeof(char)*SIZE);

    if(p == NULL)
    {
        perror("malloc failed!");
        exit(0);
    }

    tmp=p;
    for(i = 0;i<SIZE;i++){
        *p= i;
        printf("the init p==%d\n",*p);
        p++;
    }
    for(i = 0;i<SIZE;i++){                         
        printf("the result p[i]==%d\n",tmp[i]);
    }
    free(tmp);
    return 0;
}

報錯：

 p=(int*)malloc(sizeof(char)*SIZE);

修改：

    p=(int*)malloc(sizeof(int)*SIZE);

解決了， 正確使用malloc 函數
