C语言指针一道简单的编程题

按照你的要求编写的C语言程序如下

includestdio.h

int main()

{

int a,b;

int *p=a;

a=30;

printf("a=%d\n",*p);

p=b;

scanf("%d",p);

a=*p+24;

printf("a=%d,b=%d",a,b);

return 0;

}

运行结果

a=30

76

a=100,b=76

#include "stdio.h"

void Sum(int (*p)[3],int total[],int n)//n是总行数

{

int i,j;

for(i=0;in;i++)

{

for (j=0;j3;j++)

{

total[i]=total[i]+*(*(p+i)+j);

}

}

}

int main()

{

int a[2][3]={};

int total[2]={0,0};

int i,j;

printf("输入数组a:\n");

for(i=0;i2;i++)

{

for (j=0;j3;j++)

{

scanf("%d",a[i][j]);

}

}

Sum(a,total,2);

printf("各行的和:\n");

for(i=0;i2;i++)

printf("%d\n",*(total+i));

return 0;

}
