Instructions you Will Write A Flowchart And C Code For A Program That Instructions you Will Write A Flowchart And C Code For A Program That Instructions You will write a flowchart, and C code for a program that does the following: Call three functions from main(). The functions are named first(), second(), and third(). Each function prints out its name ("first," "second," "third."). After all three functions are called, the main() function should print "End of program." Here is what the program looks like.

Write a flowchart and C code for a program that calls three functions

Write a flowchart and C code for a program that calls three functions

This assignment involves designing a simple C program with a clear flowchart representation and corresponding source code. The purpose is to demonstrate understanding of function calls, control flow, and output statements in C programming language. The program must contain three separate functions—named first(), second(), and third()—each responsible for printing their respective function name. The main() function will orchestrate the sequence by calling these three functions in order, and then finally print "End of program," indicating the conclusion of the program’s execution.

To accomplish this, the process begins with creating a flowchart that visually depicts the sequence of operations: start, call to first(), call to second(), call to third(), and end with a print statement in main() that displays "End of program." Once the flowchart is completed and verified, the next step involves writing the C code that implements this logic, ensuring each function prints its name exactly as specified. The code should include proper function prototypes, definitions, and a main() function that manages the control flow appropriately.

For submission, students must upload three items:

  1. A flowchart file created with Flowgorithm, illustrating the sequence of function calls and program flow.
  2. The C source code implementing the described program, saved as a .c file.
  3. A screenshot of the program’s output when executed, saved within a Word document for easy review.

Creating an organized, well-commented code along with an accurate flowchart ensures clarity in demonstrating understanding of fundamental programming concepts. The final output should produce the expected lines:

  • first
  • second
  • third
  • End of program

This assignment emphasizes the importance of structured programming and visual representation of algorithms, which are foundational skills in computer science education.

Solution: C Code with Flowchart Description

Flowchart Overview

The flowchart starts with a start node, then proceeds to the main process where the functions first(), second(), and third() are called sequentially. Each function is represented as a process block that prints their respective string. After all functions are called, the main() function prints "End of program" and the flowchart ends.

Sample Flowchart Steps

  1. Start
  2. Main() begins
  3. Call first() -> prints "first"
  4. Return to main()
  5. Call second() -> prints "second"
  6. Return to main()
  7. Call third() -> prints "third"
  8. Return to main()
  9. Main() prints "End of program"
  10. End

C Code Implementation

Below is the C program implementing the described flow.

#include <stdio.h>

// Function prototypes


void first();


void second();


void third();


int main() {


// Call the functions in sequence


first();


second();


third();


// Print end message


printf("End of program\n");


return 0;


}


// Function definitions


void first() {


printf("first\n");


}


void second() {


printf("second\n");


}


void third() {


printf("third\n");


}

Execution Output

When compiled and run, the program will output:

first

second


third


End of program

Summary

This simple program demonstrates fundamental programming concepts including function definitions, function calls, string outputs, and program flow control. Creating an accompanying flowchart helps visualize the process, which is crucial for developing more complex algorithms.
