写一个程序 第一个字母大写 然后把语句中的元音字母(a,e,i,o,u)去掉 并且以CTRL+D结尾
不能用scanf,fgets,数组
需要使用getchar putchar
这是我的代码
但是不能以ctrl+D结尾 能帮我看看怎么修改吗?
#include <stdio.h>
#include <ctype.h>
int is_vowel(int character) {
if (character == 'a' || character == 'e' ||
character == 'i' || character == 'o' ||
character == 'u') {
return 1;
}
return 0;
}
int main(void) {
int c;
while(1) {
while( (c=getchar()) != EOF){
if (is_vowel(c) == 0) {
putchar(c);
}
} putchar('\n');
}
}
外层while(1) 循环多余:
#include <stdio.h>
#include <ctype.h>
int is_vowel(int character) {
if (character == 'a' || character == 'e' ||
character == 'i' || character == 'o' ||
character == 'u') {
return 1;
}
return 0;
}
int main(void) {
int c;
//while (1) {
while ((c = getchar()) != EOF) {
if (is_vowel(c) == 0) {
putchar(c);
}
} putchar('\n');
//}
return 0;
}
ctrl+D的ascll码为4
25,26行改成这样
while( (c=getchar()) != 4){
if (is_vowel(c) == 0&&is_vowel(c+32)==0) {
