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

read character s using scanf()

for loop iterates and check each character whether it is  s. if(str[i]==s) then prints I, else moves to next character.
