Displaying the count of each character in a string

In this recipe, you will learn how to create a program that displays the count of each character in a string in a tabular form. 

How to do it…

1. Create a string called str. The last element in the string will be a null character, \0. 
2. Define another string called chr of matching length, to store the characters of str:

3. Prompt the user to enter a string. The entered string will be assigned to the str string:

printf("Enter a string: ");
scanf("%s",str);

n=strlen(str);

5. Define an integer array called count to...
