C Exercises: Print the corresponding Fahrenheit to Celsius and Celsius to Fahrenheit
C Basic Declarations and Expressions: Exercise-95 with Solution
Write a C program to print the corresponding Fahrenheit to Celsius and Celsius to Fahrenheit.
Both cases initial tempratue = 00, maximum temperature = 1500 and step 100.
Sample Solution:
C Code:
#include <stdio.h>
int main()
{
float f_temp,c_temp;
float start_temp, end_temp;
int STEP;
start_temp = 0;
end_temp = 150;
STEP = 10;
printf("Fahrenheit to Celsius");
printf("\n---------------------\n");
printf("Fahrenheit Celsius\n");
while (start_temp <= end_temp)
{
f_temp = start_temp * 9 / 5 + 32;
printf("%6.1f \t %8.1f\n", start_temp, f_temp);
start_temp = start_temp + STEP;
}
start_temp = 0;
end_temp = 150;
STEP = 10;
printf("\n\nCelsius to Fahrenheit\n");
printf("---------------------\n");
printf("Celsius Fahrenheit\n");
while (start_temp <= end_temp)
{
c_temp = (start_temp - 32) * 5 / 9;
printf("%6.1f \t %8.1f\n", start_temp, c_temp);
start_temp = start_temp + STEP;
}
}
Sample Output:
Fahrenheit to Celsius --------------------- Fahrenheit Celsius 0.0 32.0 10.0 50.0 20.0 68.0 30.0 86.0 40.0 104.0 50.0 122.0 60.0 140.0 70.0 158.0 80.0 176.0 90.0 194.0 100.0 212.0 110.0 230.0 120.0 248.0 130.0 266.0 140.0 284.0 150.0 302.0 Celsius to Fahrenheit --------------------- Celsius Fahrenheit 0.0 -17.8 10.0 -12.2 20.0 -6.7 30.0 -1.1 40.0 4.4 50.0 10.0 60.0 15.6 70.0 21.1 80.0 26.7 90.0 32.2 100.0 37.8 110.0 43.3 120.0 48.9 130.0 54.4 140.0 60.0 150.0 65.6

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
