Program Explanation

Get a String using fgets() function.

Str -> reads the string and stores it in str.

50 -> reads maximum of 50 characters stdin-> reads character from keyboard ASCII value of A to Z is 65 - 90 and a to z is 97 to 122.

for loop iterates and check each character whether it is s A to Z, if it is in A to Z then increment it with 32 to get Lower Case.
