You must have learn multiplication tables in your school days.
This C program asks user to input a number to display its multiplication table. This can be easily achived using a for loop.
Variables :
1.
number : (Datatype int) : to hold a number entered by user.
2.
i : (Datatype int) : is assigned a initial value as 0. This variable is used for iteration
Loop :
One
for loop is used to compute the multiplication table for the inputted number.
Functions :
printf() : is used to display something on the console/screen. Format specifier %d in printf function is used to display a int variable on screen. \n is used to add a newline
scanf() : is used to fetch data inputted by the user on the console/screen using keyboard.
%d in scanf is indicates that inputted text is of type int.

Output :
Program to Generate Multiplication Table :
Enter number to generate Multiplication Table :
Multiplication Table of 13 :
=============================
0 x 13 = 0
1 x 13 = 13
2 x 13 = 26
3 x 13 = 39
4 x 13 = 52
5 x 13 = 65
6 x 13 = 78
7 x 13 = 91
8 x 13 = 104
9 x 13 = 117
10 x 13 = 130
You can also achive this by using a
while loop,
