Given a string, convert the characters of the string into opposite case,i.e. if a character is lower case than convert it into upper case and vice-versa.
Input : geeksForgEeks Output : GEEKSfORGeEKS Input : hello every one Output : HELLO EVERY ONE
ASCII values of alphabets: A – Z = 65 to 90, a – z = 97 to 122
- Take one string of any length and calculate its length.
- Scan string character by character and keep checking the index .
- If character in a index is in lower case, then subtract 32 to convert it in upper case, else add 32 to convert it in upper case
- Print the final string.
Note: This program can alternatively be done using C++ inbuilt functions – Character.toLowerCase(char) and Character.toUpperCase(char).
