• Task
1. Write the reverse string() function for the given code below. (Hint: use strlen() function which gives the length of a string.)
• # include < stdio .h >
• # include < string .h >

2. Write print line(), print histogram() and len() functions for the given code below.
print line() : Prints <int num of chars> times <char c> character.
print histogram() : Prints a histogram of <int values[]> with <char c> using print print line() and len() functions.
len() : Returns the length of <int array[]>.
• # include < stdio .h >

Sample:
Enter positive integer(s), to print an histogram.
Enter a non-positive integer to stop.
Enter a value: 3
Enter a value: 5
Enter a value: 6
Enter a value: 2
Enter a value: -1
Output:
