Times table

Multiplication table - C programming example

This C program will take the desired number as input. Output will show the times table of the desired number.

C Programming Example
Times Table

C Programming Code

#include<stdio.h>
#include<conio.h>

main()
{
    int a,i;
    printf("enter any number \n");
    scanf("%d",&a);

    for (i=1;i<=10;i++)
    printf("%3d*%3d=%3d \n",a,i,a*i);
    getch();

}

Output of the C program code

C Programming example
Times table of 15

Explanation of the C Program

        #include<stdio.h>
#include<stdio.h>
Ø This are called header file.A header file is a file with extension .h which contains C function declarations and macro definitions to be shared between several source filesThe C programming language provides many standard library functions for file input and output. These functions make up the bulk of the C standard library header<stdio.h>.In the other hand<conio.h> is a C header file used mostly by MS-DOS compilers to provide console input/output. It is not part of the C standard library or ISO C.This header declares several useful library functions for performing "console input and output" from a program.
·       main()
Ø In C, program execution starts from the main() function. The main function can in-turn call other functions. When main calls a function, it passes the execution control to that function. The function returns control to main when a return statement is executed or when end of function is reached.
·       int a,i;

Ø An integer is a  whole number (not a fraction) that can be positive, negative or zero.Therefore, the numbers 10,0, 25 and 5.148 are all intergers.Unlike floating point numbers,integers cannot have decimal place.Here we declare “a”and  “i” variable in  integer type. So this two variable cannot  take values containing decimal number.
·       printf() function
Ø C uses printf() function to write from the input devices. This function has been declared in the header file called stdio.h. Any text written within the pair of quotes ("") is displayed as such by printf() function on the screen. 
·       scanf() function
Ø This function is used to get input from the user of the program.scanf(“%d”,&a”)is used here. So, this program will read in a integer value for “a” variable that the user enters on the keyboard(%d is for float values.
·       printf("%d*%d=%d \n” a,i,a*i );
Ø %d is used to print the main result.
·       getch() function
Ø getch() is used to hold the console(output) window on the screen after the whole program run is completed till the user enters a key from keyboard. This function is present in the header file called conio.h.

This program will show you the multiplication table of any number. What you need to do is, just input the number.
