The Following Program Uses A Loop And Calls A Function Calle

The Following Program Uses A Loop And Calls A Function Called Firstfun The following program uses a loop and calls a function called firstFunction() five times, each time passing an argument that is the value of the counter. Each time it calls the function, a new message is printed. Then firstFunction() calls secondFunction(), without arguments. When control returns to main(), main() calls thirdFunction(). Again, we prototype both functions. Here's the flowchart: And here is the code: And here is the output: Now, type the code into your compiler. (No flowchart this time) Upload your .c file and a screenshot of your code output saved in a Word document including the path name directory at the top of the screen into the dropbox for grading.

Paper For Above instruction This paper presents a comprehensive C programming exercise involving function calls, loops, and control flow to demonstrate fundamental programming concepts. The exercise aims to enhance understanding of function prototypes, argument passing, function invocation, and program debugging. The task involves writing a C program based on a given description, implementing the required functions, executing the code, and documenting the output for assessment.

Introduction C programming is renowned for its efficiency and control, enabling developers to create complex applications with relative ease. Mastery of functions, loops, and control flow constructs is essential for writing clear, reusable, and maintainable code. This exercise provides practical experience in implementing these core concepts through a specific programming task that involves calling multiple functions in a nested and sequential manner.

Problem Description The task requires developing a C program that iterates using a loop and calls a function named firstFunction() five times. Each call passes an increasing counter value as the argument. Inside firstFunction() , the program prints a message indicating the invocation along with the argument value, then calls secondFunction()

without arguments. Once secondFunction() completes, control returns to main() , which subsequently calls thirdFunction() .

The program should be properly prototyped, and the flow of execution should mirror the described sequence. After implementing the code, students are expected to compile it, observe the output, and prepare a document containing the code screenshot and directory path for submission.

Implementation Details The main function initializes the sequence with a loop that iterates five times. During each iteration, firstFunction() is invoked with the loop counter as the argument. In firstFunction() , a message is printed indicating the function call and the argument received. Then, secondFunction() is called, which merely prints a message signifying its execution. After control returns to main() , thirdFunction() is called, which again prints a message. This process demonstrates nested function calls and the flow of control within a C program.

Sample Code

#include // Function prototypes void firstFunction(int num); void secondFunction(); void thirdFunction(); int main() { int i; for (i = 1; i <= 5; i++) { firstFunction(i); } // Call thirdFunction after loop completes thirdFunction(); return 0; } void firstFunction(int num) { printf("firstFunction called with argument: %d\n", num); secondFunction(); // Call secondFunction } void secondFunction() { printf("secondFunction is executing.\n"); } void thirdFunction() { printf("thirdFunction is executing.\n");

} Program Output firstFunction called with argument: 1 secondFunction is executing. firstFunction called with argument: 2 secondFunction is executing. firstFunction called with argument: 3 secondFunction is executing. firstFunction called with argument: 4 secondFunction is executing. firstFunction called with argument: 5 secondFunction is executing. thirdFunction is executing.

Conclusion Through this exercise, students gain practical experience with function calls, argument passing, and control flow in C. The clear sequence of function execution exemplifies how nested calls work and how flow returns back to calling functions. Such exercises lay the groundwork for developing more sophisticated programs by understanding fundamental concepts thoroughly.
