c语言:在主函数中输入3个数,调用sum函数实现这三个数的加法运算.子函数sum实现两个实数的加法运算

Answer 1

int sum(int x,int,y)
{int z;
z=x+y;
return z;
}

int main()
{int a,b,c;
scanf("%d,%d,%d",a,b,c);
printf("%d\n",sum(sum(a,b),c));
return 0;
}

Answer 2

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

int sum(int x,int y)
{return x+y;}

void main(){
int a,b,c;
printf("Please input three number:");
scanf("%d%d%d",&a,&b,&c);
printf("Sum=%d\n",sum(sum(a,b),c));
system("pause");
}
