编程学习网为您整理以下代码实例，主要实现：C语言isspace()库函数，希望可以帮到各位朋友。
#include <stdio.h>
#include <ctype.h>
int main () {
int var1 = 't';
int var2 = '1';
int var3 = ' ';
if( isspace(var1) ) {
printf("var1 = |%c| is a white-space character\n", var1 );
} else {
printf("var1 = |%c| is not a white-space character\n", var1 );
}
if( isspace(var2) ) {
printf("var2 = |%c| is a white-space character\n", var2 );
} else {
printf("var2 = |%c| is not a white-space character\n", var2 );
}
if( isspace(var3) ) {
printf("var3 = |%c| is a white-space character\n", var3 );
} else {
printf("var3 = |%c| is not a white-space character\n", var3 );
}
return(0);
}
