Section 1.3 The for statement¶

Question¶

There are plenty of different ways to write a program for a particular task. Let’s try a variation on the temperature converter using for loop.

Program¶

#include <stdio.h>

/* print Fahrenheit-Celsius table */
int main() {
    int fahr;
    for (fahr = 0; fahr <= 300; fahr = fahr + 20)
        printf("%3d %6.1f\n", fahr, (5.0 / 9.0) * (fahr - 32));
}

Explanation¶

In this program we are going to convert a given Fahrenheit temperature to Celsius temperature using the formula C=(5/9)(F-32) using a for loop

for (fahr = 0; fahr <= 300; fahr = fahr + 20)
        printf("%3d %6.1f\n", fahr, (5.0/9.0)*(fahr-32));
