Program to convert temperature from farenheit to celcius or vice versa in C

Logic:

1. Formula for temperature conversion is:
2. C=(F-32)*5/9
3. F=9/5 * C +32

Algorithm

1. Enter choice ch
2. if (ch == 1)
3. {
4. printf(“enter the value of temperature in Celcius\n”);
5. scanf(“%f”, &celcius);
6. f = (celcius * 9 / 5) + 32;
7. printf(“the value of temperature in fahrenheit is %f”, f);
8. }
9. else
10. {
11. printf(“enter the value of temperature in fahrenheit\n”);
12. scanf(“%f”, &f);
13. celcius = (f – 32) * 5 / 9;
14. printf(“the value of temperature in celcius is %f”, celcius);
15. }
