c - 我在编译这个 c 程序时遇到这些错误

Question

#include<stdio.h>
  main()
  {
     int num1,num2,sum;
     printf("Enter the two integers to be added");
     scanf("%d %d", &num1, &num2);
     sum = num1+num2;
     printf("Addition of %d and %d = %d", num1, num2, sum);
  }

我得到的错误是:

1. Unable to open include file 'stdio.h'

2. Function printf should have a prototype.

3. Function scanf should have a prototype.

Answer 1

确保您已正确安装 C 编译器。如果您使用的是 Linux 操作系统，那么它是预先安装的。
