Using strcmp ?

[fouzimedfouni]

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

int main()
{
    char myfruit[] = "apple";
    char guessing[20];
    
        printf("Guess my favorite fruit? ");
        scanf("%20s", guessing);
    
        if (strcmp (myfruit, guessing) == 0)
            puts("Correct answer!");
        else ("not correct");
        
        fflush(stdin);
    
    getchar();

}

need some help here , thank you

Just from looking:

1. The case where it isn't apple - I think you meant to call puts("not correct"); but if you look carefully, you did not.

2. There is the chance that input which contains "apple" still does not compare with apple. Consider cases where the user accidentally types something before or after apple, or perhaps the user types just enough characters that there is not room for the scanf() function to append a zero to the string. Yes, that can happen.

3. fflush(stdin); does not work everywhere.

That said, something like this should work within reason.

#include <stdio.h>
#include <string.h>
int main(void) {
	const char myfruit[] = "apple";
	char guessing[20];

	printf("Enter fruit: ");
	scanf("%19s", guessing);
	if (strcmp(myfruit, guessing) == 0) {
		puts("Correct!");
	}
	else {
		puts("not correct");
	}
	return 0;
}

thank you my friend I compared your Code to mine and deleted some of your stuff like CONST and I added FFLUSH, and GETCHAR even I know a lot of compilers warning from using them, but I tried them though cause I wanted to know where did I go wrong and sure enough I forget to put something so simple which it (puts("not correct"); ) for ELSE ....lol
thank you for your response
