程序中的这个杂散错误是什么

Question

代码：

#include<stdio.h>
#include<conio.h>
int main()
{
    int a,b,c;
    printf("addition of two numbers\n");
    scanf("%d%d",&a,&b);
    c = a + b;
    printf("%d",c,\n);
    printf("subtraction of two numbers\n");            
    scanf("%d%d",&a,&b);
    c = a - b;
    printf("%d",c \n);
    return 0;


}

错误：

Answer 1

您的两个printf()命令：

printf("%d",c,\n);

和

printf("%d",c \n);

在换行符周围缺少引号（一个逗号）。他们应该看起来像这样：

printf("%d \n",c);
