MCS-011 Q3 Explanation
Q4. (2 ½ X 4 =10 Marks)
Write the following string functions that:
a) Replace a character in a given string with a character suggested by the user.
b) Convert the given string into uppercase.
c) Convert the alternate character into upper case.
d) Check each and every character in the string and display whether it is an alphabet, digit or special character.
