What is wrong with this code?

Question

Using a do…while() loop, continuously scan for characters (one per line) and print it out afterwards.
The loop shall terminate due to either of the following reasons:
The inputted character is a vowel
The number of inputted characters has already reached 5.
It must also be guaranteed that if the number of inputted characters is less than 5, then there must be a vowel from among the inputted characters.

(I tried answering this problem with this code here: https://code.sololearn.com/cA7a5A8a19a1/#)

But i cant get all test cases correct, only 3/4. What am i doing wrong? Also i cant check what the 4th test case its because its hidden. Help?

Answer 1

run loop upto 4 becz count Start from 0 and till upto 4
#include <stdio.h>
#include <string.h>
#include <ctype.h>

int main(){
char letter;
int count=0;
do{
scanf("%c", &letter);
char c = tolower(letter);
if(c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u') {
printf("%c",c);
break;
}
printf("%c",c);
count++;
} while(count<4);
return 0;
}

Answer 2

Try to change your (while count<10) to (while count<5)

Answer 3

《 Nicko12 》 Doesn't work. Its restricting me to only 3 inputs now

Answer 4

Mint
What about while(count < 7) ? This should get 5 inputs.

Answer 5

If you're giving input with single letter per line seperated by newline . Use scanf("%c\n", letter).

And in while loop check use 5 instead of 10
While (count!=5) it will exit after count reaches 5.

I also have checked and confirmed here.

Hope this helps .

Answer 6

♨️♨️ Nope. Its only allowing me 2 character inputs

Answer 7

《 Nicko12 》 Just tried. Only 4 inputs

Answer 8

Is there input is accepted like "abcde" or
line by line like
a
b
C
D
E

For 1st order use
scanf("%c", &letter);
and
while(count<5);

For 2nd order type, use :
scanf("%c\n", &letter);
and while(count<5);

1st one, reads charecter by charecter only while 2nd one reads new line also and I gores it then reads next charecter.
Hope it helps...

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

int main(){
char letter,c;
int count=0;
do{
scanf("%c", &letter);
c = tolower(letter);
if(c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u') {
printf("First Vowel is");
break;
}

count++;
} while(count<5);
printf("%c",c);
return 0;
}
