Loop Exercises

Loop programming exercises and solutions in C

In programming, there exists situations when you need to repeat single or a group of statements till some condition is met. Such as - read all files of a directory, send mail to all employees one after another etc. These task in C programming is handled by looping statements.

Looping statement defines a set of repetitive statements. These statements are repeated with same or different parameters for a number of times. Looping statement is also known as iterative or repetitive statement.

C supports three looping statements.

for loop

while loop

do...while loop

In this exercise we will practice lots of looping problems to get a strong grip on loop. This is most recommended C programming exercise for beginners.

Always feel free to drop your queries, suggestions, hugs or bugs down below in the comments section. I always look forward to hear from you.

Required knowledge

Basic C programming, Relational operators, Logical operators, If else, For loop
