hello everyone i am new to this community . i am having a problem right now with arrays. So basically this program let user to enter anything in lowercase and then convert it to uppercase(if user input uppercase it will stay the same). Because i am not allowed to use toupper(), i subtract 32 from lower case ASCII code so that i get upper case.
my problem is the console output,as you can see '╠' these are weird characters. can anyone tell me how to omit those in the console output?
Please Enter a string of 80 or fewer characters

}
else if (line[count] >=65 && line[count] <=90); //check if there are uppercase in userinput.
{
line[count] = line [count]; //upper case stay the same.
}
