#include <stdio.h>

void delete_char(char *str, char ch) {
  int i, j;
  int len = strlen(str);

  for (i = j = 0; i < len; i++) {
    if (str[i] != ch) {
      str[j++] = str[i];
    }
  }
  str[j] = '\0'; 
}

int main() {
  char str[100];
  char ch;

  printf("Enter a string: ");
  fgets(str, 100, stdin);

  printf("Enter character to delete: ");
  scanf(" %c", &ch);

  delete_char(str, ch);

  printf("String after deletion: %s\n", str);

  return 0;
}

Enter a string:
Enter character to delete:
