Remove Character from C String

To remove a specified character, you can use two pointers to traverse the string and keep the characters that should not be deleted. Below is an example program:

#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;
}

In the example above, the removeChar function takes a string and a character as parameters, then iterates through the string to keep only the characters that are not equal to the specified character. Finally, it prints out the modified string.
