Tutorial 15: Temperature Conversion Program

Overview

• Objective: Write a program to convert temperature from Celsius to Fahrenheit.
• Program Name: temperature_conversion.c
• Complexity: Simple, fun exercise focusing on basic input-output and calculations in C.

Program Structure

• File Name: temperature_conversion.c

Code Breakdown

1. Comments:

   • Line 1-2: // Input temperature in degree Celsius and convert to degree Fahrenheit

2. Header File:

   • Line 3: Include standard header files needed for input-output operations.

3. Main Function:

   • Line 4: Declare main() function.
   • Add curly braces for function scope.

4. Variable Declaration:

   • Declare a variable temp of type float to store the temperature in Celsius.

Input and Output

• Input:

  • Use printf to prompt the user to input temperature in Celsius.
  • Use scanf to read the input value.
  • Use %f format specifier for floating-point numbers.
  • Store result in temp using address-of operator &temp.

• Output:

  • Display equivalent temperature in Fahrenheit.
  • Use printf with a message and %f to show the computed value.

Conversion Formula

• Formula:
  • Multiply the Celsius temperature by 1.8 and add 32 to convert to Fahrenheit.
  • No parentheses needed due to operator precedence (multiplication before addition).

Example Execution

• Example: Input 37 Celsius should output 98.6 Fahrenheit.
• Note: 37 Celsius is normal body temperature.

Conclusion

• Summary: A very simple program with only 4 lines of executable code.
