C Program to Convert Celsius to Fahrenheit Temperature

C program to convert Celsius to Fahrenheit temperature.

In this article, you will learn how to make a C program to convert Celsius to Fahrenheit temperature.

 

Example

 

You should have the knowledge of the following topics in c programming to understand this program:

• C Functions
• C main() Function
• C printf() Function
• C while loop
• C Data Types

 

Standard Formula

 

Where

• F is the fahrenheit unit
• C is the celsius unit

 

In this article, we solved this problem in four methods:

1. Using the normal calculation
2. Using the while loop
3. Using the function
4. Using the pointer

C Program to Convert Celsius to Fahrenheit Temperature

// C Program to Convert Celsius to Fahrenheit Temperature
#include <stdio.h>

int main() {
    float c, f;
    
    // c - To store the celsius
    // f - To store the fahrenheit

    printf("Enter the temperature in Celsius::\n");
    scanf("%f", &c);

    /* celsius to fahrenheit conversion formula */
    f = (c * 9 / 5) + 32;

    // Final Output
    printf("\n%f Celsius = %f Fahrenheit\n", c, f);
    return 0;
}
