[Tutorial 7] 14.Write a program that converts inches to centimeters. For example, if the user enters 16.9 for a Length in inches, the output would be 42.926cm. (Hint: 1 inch = 2.54 centimeters.)

#include <stdio.h> int main() { float inches, centimeters; /*Input length in inches from the user*/      printf( "Enter length in inches: " );      scanf( "%f" , &inches); /*Convert inches to centimeters*/      centimeters = inches * 2.54; /* Display the result */      printf( "%.2f inches is equal to %.3f centimeters\n" , inches, centimeters); return 0; }

[Tutorial 7] 10.Convert the given temperature in Celsius to Fahrenheit. T(°F) = T(°C) × 1.8 + 32

#include <stdio.h> int main() { float celsius, fahrenheit; /* Input temperature in Celsius from the user*/      printf( "Enter temperature in Celsius: " );      scanf( "%f" , &celsius); /* Convert Celsius to Fahrenheit*/      fahrenheit = celsius * 1.8 + 32; /* Display the temperature in Fahrenheit*/      printf( "%.2f Celsius is equal to %.2f Fahrenheit\n" , celsius, fahrenheit); return 0; }
