If ASCII code is in between 65 to 90 inclusively, then it is upper case. For all lowercase letter Assign corresponding ASCII code(97-122) to that place in string. And Vice-versa for Lower to Uppercase. Try first to code self , If you still find hard to execute then check the code below -- // For Uppercase to all Lowercase letter std::string str="%^#AdKLdsSD*("; for( int i=0; i= 65 && s[i] <= 90 ) { s[i] = (s[i]-65)+97 //find diff between Uppercase Character and 'A' and then add ASCII value of 'a' } } Similarly for lowercase with different ASCII if condition and if block statement. For better coding style :: You can wrap these thing into a function. read less
