C Program

#include<stdio.h>
int main()
{
    float f,c;
    int choice;
    printf("--- Menu ---\n");
    printf("1. Celsius to Fahrenheit.\n");
    printf("2. Fahrenheit to Celsius.\n");
    printf("Enter choice :");
    scanf("%d",&choice);
    if(choice == 1)
    {
        printf("Enter the Temperature in Celsius :");
        scanf("%f",&c);
        f=(c*9)/5+32;
        printf("Temperature in Fahrenheit is:%.2f",f);
    }
    else if(choice ==2)
    {
        printf("Enter the Temperature in Fahrenheit :");
        scanf("%f",&f);
        c=(f- 32)*5/9;
        printf("Temperature in Celsius is:%.2f",c);
    }
    else
    {
        printf("INVALID option.");
    }
    return 0;
}

Output

Menu —
1. Celsius to Fahrenheit.
2. Fahrenheit to Celsius.
Enter choice :2
Enter the Temperature in Fahrenheit :98.4
Temperature in Celsius is:36.89
