c语言中， 字符型变量的输入中，getchar怎么用？最好举个例子，谢谢！

Question

如题所述

Answer 1

getchar()就是输入一个字符的意思，相当于scanf("%c",&d),变量d已经定义为字符型

举个简单的例子

#include <stdio.h>
void main()
{
char d;
d=getchar();
printf("%c\n",d);

}

输入一个d,将输出d

Answer 2

c = getchar();
is an expression and has a value, which is the value of the left hand side after the assignment.
This means that a assignment can appear as part of a larger expression. If the assignment of a
character to c is put inside the test part of a while loop, the copy program can be written this
way:
#include <stdio.h>
/* copy input to output */
main()
{
int c;
while((c = getchar()) != EOF)
putchar(c);
}追问

Answer 3

这个问题比较抽象，遇到这种问题，自己写一个程序试试，比如：

#include <stdio.h>
#include <iostream>
int main()
{
    char a;
    a=getchar();
    printf("%c\n",a);
    system ("pause");
    return 0;
}

输入 abc
输入 a
