求两数之和 用C语言怎么写 谢谢（c语言求两数的平方和）

直接求两数之和include<stdio.h>int main (){int a,b,sum; //申明a,b,sum为整型

a=1;b=1; //给a,b赋值,这里a,b自己定

sum=a+b; //求和

printf{"the sum is %d",sum}; //输出sum的值

return (0);}

求输入的两数之和#include<stdio.h>int main (){int a,b,sum;

printf{"Please enter x,y:"}; //提示输入x,y

scanf{"%d,%d",&a,&b}; //将输入的值赋给a,b

sum=a+b; //求和

printf{"the sum is %d",sum}; //输出sum的值

return (0);

}
