Exercise 3-1. Write a program that will first allow a user to choose one of two options:
1. Convert a temperature from degrees Celsius to degrees Fahrenheit.
2. Convert a temperature from degrees Fahrenheit to degrees Celsius.
the program should then prompt for the temperature value to be entered and output the new value that results
from the conversion. to convert from Celsius to Fahrenheit you can multiply the value by 1.8 and then add 32.
to convert from Fahrenheit to Celsius, you can subtract 32 from the value, then multiply by 5, and divide the
result by 9
ME:
1 #include<stdio.h> 2 int main(void) 3 { 4 double farenheit = 0; 5 double centigrate = 0; 6 int type = 0; 7 8 //get the temperature 9 printf ("please enter your temperature, 1 for farenheit or 2 for centigrate"); 10 scanf ("%d", &type); 11 12 if (type = 1 ){ 13 printf("pls enter the number of your farenheit"); 14 scanf("%d", &farenheit); 15 centigrate = (farenheit - 32)*5/9; 16 printf("farenheit to centigrate is %d ", farenheit, centigrate); 17 } 18 else { 19 printf("pls enter your number of centigrate"); 20 scanf("%d", ¢igrate); 21 centigrate = farenheit * 1.8 + 32; 22 printf("farenheit to centigrate is %d", centigrate); 23 24 } 25 26 return 0; 27 } 28
