c语言字符串怎么删除指定字符

要删除一个指定的字符，可以使用两个指针来遍历字符串，并将不需要删除的字符保留下来。下面是一个示例程序：

#include <stdio.h>
#include <string.h>

void removeChar(char *str, char c) {
    int i, j = 0;
    for (i = 0; str[i] != '
#include <stdio.h>
#include <string.h>
void removeChar(char *str, char c) {
int i, j = 0;
for (i = 0; str[i] != '\0'; i++) {
if (str[i] != c) {
str[j++] = str[i];
}
}
str[j] = '\0';
}
int main() {
char str[] = "Hello, World!";
char c = 'l';
printf("Original string: %s\n", str);
removeChar(str, c);
printf("String after removing '%c': %s\n", c, str);
return 0;
}
'; i++) {
        if (str[i] != c) {
            str[j++] = str[i];
        }
    }
    str[j] = '
#include <stdio.h>
#include <string.h>
void removeChar(char *str, char c) {
int i, j = 0;
for (i = 0; str[i] != '\0'; i++) {
if (str[i] != c) {
str[j++] = str[i];
}
}
str[j] = '\0';
}
int main() {
char str[] = "Hello, World!";
char c = 'l';
printf("Original string: %s\n", str);
removeChar(str, c);
printf("String after removing '%c': %s\n", c, str);
return 0;
}
';
}

int main() {
    char str[] = "Hello, World!";
    char c = 'l';
    
    printf("Original string: %s\n", str);
    removeChar(str, c);
    printf("String after removing '%c': %s\n", c, str);

    return 0;
}

在上面的示例程序中，removeChar函数接受一个字符串和一个字符作为参数，然后遍历字符串，将不等于指定字符的字符保留下来。最后将修改后的字符串打印出来。
