I understand how to do it after i am able to read one character at a time but its only this one part that i do not know how to do. I am not allowed to use strings and arrays. I am only allowed to use logical operations, conditional statements and loops so yeah... plz help cause this is really puzzling me.

All you need to do is read one character at a time, and have another variable to keep track of the "highest" letter found so far.

how do i read one character at a time though? cause doesnt scanf only read 1 character and then its done reading the input. I am not allowed to repeatedly press enter btw.

If you use a char variable, it will only read one character at a time, even if you typed in more than one. Use a loop to grab the characters in sequence.

could you elaborate how to grab the characters in sequence. i found out that you use scanf("%c%c", &a, &b); a and b are variables. how would i keep grabbing characters though. could someone plz show me the format of the loop with the scanf inside?

while (input != '\n')
{
scanf("%c", &input);
//do stuff
}

wouldnt you have to keep inputing the character sequence though because it goes scanf you put something then it goes scan f again and you would have to put something again right?

ok i figured this out but how do i make it print the first case of letter?

Back up a step, how do you FIND the first case? You should have it in memory, and just need to print the value.
