Computer Science: A Structured Programming Approach Using C1 4-5 Standard Functions C provides a rich collection of standard functions whose definitions have been written and are ready to be used in our programs. To use these functions, we must include their function declarations. Math Functions Random Numbers Topics discussed in this section:
