#include <stdio.h>
int main()
{
int integer1,integer2,sum;
printf("enter first integer\n");
scanf("%d",&integer1); error:statement missing in function main
printf("enter second integer\n");
scanf("%d",&integer2);
sum=integer1+integer2; warning: possible use of "integer1"before definition in function main
printf("sum is %d\n",sum);
return 0;
}
这个提示是什么意思啊??!!!
