int ascii = int(c);
if(ascii >= 97 && ascii <=122)
return char(ascii-32);
else return c;
}
int main(){
char inp[40];
cin.getline(inp,40);
int len = 0;
for(len=0;inp[len]!='\0';len++)
inp[len] = toUP(inp[len]);
for(int j=0;j<len;j++) cout<<inp[j];
return 0;
}

Answer 2

what you need ?

acc to ur question , I added no library

if user enters wrong charecter the program will automatically detect it.

what logic ?

there is a simple logic​ if the character is smaller case decrease 32 to get the uppercase

Answer 3

I don't know C++, but I wrote it in a language I do know anyway

myString="i am programmer"

for c in myString:
if c==" ":
print(" ",end='')
else:
num=ord(c)-32
let=chr(num)
print(let, end='')

Output:
I AM PROGRAMMER
