C Exercises

[abhijangda]

Hello, friends. 2 days ago my friend asks me to create some programs in C which include some algorithms, merge sort, quick sort, binary search tables, double ended queues etc. Since, I mainly use Python for programming and have some knowledge of C, I struggled to create those programs, although I created those in Python. So, I think I should brush up my C skills.
For that currently I have book The C Programming Language by Denies M. Ritchie and Brian W. Kernighan. But I saw that there are less number of exercises available to practice. Can you tell me a good source of C programming exercises??? I mainly need exercises related to strings, arrays and pointers.
