The program needs to tell me if the phrase is a palindrome or not but when compile it and then enter a phrase it tells me everything is a palindrome..something is wrong with my functions but I cannot figure out what it is. I need some help please lol
Code:#include <stdio.h> #define true 1 #define false 0 void make_copy_of_string(char str[], char str_copy []); void keep_chars(char str[]); void convert_upper_to_lower_case(char str[]); _Bool palindromeness(char str[]); int main(void) { char phrase[101], phrase_copy[101]; printf("Enter Phrase: "); fgets(phrase, 101, stdin); make_copy_of_string(phrase, phrase_copy); keep_chars(phrase_copy); convert_upper_to_lower_case(phrase_copy); if(palindromeness(phrase_copy) == true) printf("The phrase: %s\n Is a palindrome!\n", phrase); else printf("The phrase: %s\nIs not a palindrome\n", phrase); return 0; } void make_copy_of_string(char str[] , char str_copy[]) { int i=0; while(str[i]!= '\n' && str[i] != '\0') { str[i] = str_copy[i]; i++; } str_copy[i]='\0'; str[i]='\0'; } void keep_chars(char str[]) { int i=0, j=0; while(str[i] != '\0') { if(('A' <= str[i] && str[i] <= 'Z') || ('a' <= str[j] && str[j] <='z')) { str[i]=str[j]; i++; j++; } else { i++; } } str[j]='\0'; } void convert_upper_to_lower_case(char str[]) { int i=0; while(str[i] !='\0') { if('A' <= str[i] && str[i] <= 'Z') {str[i]=str[i]+32; i++; } else { i++; } } } _Bool palindromeness(char str[]) { int i=0; char str_copy[i]; if(str[i] == str_copy[i]) { return true; } else { return false; } }
