This code is a simple program that converts kilometers to other units of length such as meters, feet, inches, and centimeters. The program uses the stdio.h library and the scanf() function to take user input for the distance in kilometers. The input is stored in the variable km.
Then, the program uses mathematical formulas to convert the distance in kilometers to other units of length. The formulas are as follows:
m = km * 1000;
ft = km * 3280.84;
inch = km * 39370.1;
cm = km * 100000;
Finally, the program uses the printf() function to print the converted distances in their respective units. The program uses the format specifier %.2f to round off the values to 2 decimal places. The program returns 0 after all the calculations are done, indicating that the program executed successfully.
