用C设计C=A+B； 求C 的程序

main()
{int a,b,c
printf("请输入a和b的值！");
scanf("%d%d",&a,&b);
c=a+b;
printf("c是：%d",c);

}

#include <stdio.h>
main
{
int a,b,c;
scanf("%d，%d",&a,&b);
c=a+b;
printf("%d",c)
}

#include <stdio.h>
void main()
{int a,b,c;
printf("请输入a和b的值:");
scanf("%d%d",&a,&b);
c=a+b;
printf("c=%d",c);
}

main()
{int a,b,c
printf("please input the value of a and b:！");
scanf("%d%d",&a,&b);
c=a+b;
printf("c：%d",c);

#include <stdio.h>
main()
{
int a,b,c;
printf("please input two number:a and b ");
scanf("%d,%d",&a,&b);
c=a+b;
printf("c is: %d",&c);
}

注意第六行,在输入a和b时,中间要加一个逗号
