C Program - Generate Multiplication Table with User Input

 This program aims to generate a multiplication table for a given number that the user enters.

#include <stdio.h>

int main()
{

    int number, x;

    printf("Enter an integer: ");
    scanf("%d", &number);

    printf("Multiplication table of %d: \n", number);

    for (x = 1; x <= 10; x++)
    {
        printf("%d * %d = %d \n", number, x, number * x);
    }

    return 0;
}

Result: 

Enter an integer: 1
Multiplication table of 1:
1 * 1 = 1
1 * 2 = 2
1 * 3 = 3
1 * 4 = 4
1 * 5 = 5
1 * 6 = 6
1 * 7 = 7
1 * 8 = 8
1 * 9 = 9
1 * 10 = 10

Process returned 0 (0x0)   execution time : 4.505 s

At first, the program declares two variables, number and x, both of type int. number is the input integer that the user enters, and x is used as a loop variable to iterate over the multiplication table.

Next, the program prompts the user to enter an integer by printing the message "Enter an integer: " using the printf function. Then, the scanf function is used to read the integer entered by the user and store it in the variable number.

After that, the program prints a message using printf to indicate the start of the multiplication table for the entered integer. It uses the value of number to generate the message by using a format specifier %d which is replaced by the value of number in the output message.

The core of the program is a for loop, which iterates over the multiplication table from 1 to 10. Within the for loop, the printf function is used to print the multiplication table of the entered number. It uses format specifiers %d and %d * %d = %d \n to generate the output message. %d is replaced by the value of number and x, and %d * %d = %d \n is replaced by the result of the multiplication. The \n at the end of the format specifier indicates that a new line should be added after each iteration of the loop.

Finally, the program ends by returning 0 to the operating system to indicate that the program has completed successfully.
