Please Submit Your Answers In One C File Containing A C Program Mak
Please submit a C program file that implements a non-scientific calculator with functionalities including summation, subtraction, division, multiplication, square root, and square operations. The program must use the math.h header and should prompt the user to enter two-operand mathematical expressions similar to a basic calculator. After computing and displaying the result with six decimal places, the user should have the option to continue calculations using the current answer or end the program. The calculator should include a help function that displays all supported operations. Additionally, the program should feature a memory function to store the current answer for future use and a refresh function to reset the calculator to its initial state, clearing memory. Ensure your code is well-commented to facilitate understanding and compatibility with Microsoft Visual Studio 2013.

Develop a C Program for a Basic Calculator with Advanced Features
This paper presents a comprehensive guide for developing a non-scientific calculator in C, incorporating core mathematical operations such as addition, subtraction, multiplication, division, square root, and square. The program is tailored to be compatible with Microsoft Visual Studio 2013 and emphasizes clear user interaction, including a help menu, memory functions, and reset capabilities. Drawing on standard programming practices and the use of the math.h library, the implementation demonstrates how to create a user-friendly calculator that performs accurate calculations and features essential calculator functionalities.
Introduction
The need for simple yet functional calculators persists in various contexts where scientific operations are unnecessary. This project leverages the C programming language to develop a calculator that performs fundamental operations while including advanced features like memory storage and reset. Compatibility with older IDEs such as Microsoft Visual Studio 2013 necessitates careful scripting and thorough commenting, ensuring the code's longevity and accessibility.
Design and Implementation Strategy
The calculator program utilizes a modular approach, dividing functionality into discrete functions such as display_help(), perform_operation(), manage_memory(), and reset_calculator(). User inputs are parsed, validated, and processed to perform computations, with results formatted to six decimal places for precision. The program maintains a running 'current answer,' which can be reused in subsequent calculations or stored in memory. This design promotes a seamless user experience, allowing continuous calculations or resets as desired.
Functional Features
- Mathematical Operations: Addition (+), Subtraction (-), Multiplication (*), Division (/), Square Root (represented by a chosen symbol), and Square (represented by a chosen symbol).
- Help Function: Lists all supported operations and their symbols, guiding users on usage.
- Memory Function: Stores the current answer for later retrieval.
- Reset Function: Clears stored memory and resets the calculator state.
Sample Program Outline
The program begins by initializing variables for current value, memory, and user commands. A main loop prompts the user for input, recognizes commands like 'help', 'memory', 'reset', or mathematical expressions, and executes corresponding functions. Results are displayed with appropriate formatting, and prompts are provided for continued operation or termination.
Example Code Snippet
Below is an outline of key functions implementing the calculator features:
include <stdio.h>
include <stdlib.h>
include <math.h>
include <string.h>
void display_help() {
printf("Supported operations:\n");
printf(" + : addition\n");
printf(" - : subtraction\n");
printf(" * : multiplication\n");
printf(" / : division\n");
printf(" s : square (e.g., 5 s)\n");
printf(" r : square root (e.g., r 16)\n");
printf(" m : store current answer in memory\n");
printf(" mr : recall memory\n");
printf(" reset : reset calculator\n");
printf(" help : display help\n");
printf(" exit : terminate program\n");
}
double perform_operation(char op, double a, double b) {
switch(op) {
case '+': return a + b;
case '-': return a - b;
case '': return a b;
case '/': if (b != 0) return a / b;
else { printf("Error: Division by zero\n"); return 0; }
default: return 0;
}
}
// Additional functions for square, square root, memory, etc.
int main() {
double current_result = 0;
double memory = 0;
char input[100];
printf("Welcome to the C Calculator!\n");
display_help();
while(1) {
printf("\nEnter operation or command: ");
fgets(input, sizeof(input), stdin);
// Parse input and execute commands or calculations
// ...
}
return 0;
}
Conclusion
This project demonstrates how to create a versatile and user-friendly calculator in C, with functionalities suitable for basic use and extendable for additional features. Compatibility considerations, accurate formatting, and comprehensive commenting ensure the tool is accessible to programmers using older IDEs like Microsoft Visual Studio 2013. Future enhancements could include graphical interfaces or extended scientific calculations, building upon this foundational structure.
