Code to Generate multiplication table using for loop

In this program, we will  display multiplication table of given number using for loop in C language.

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num,i;
    printf("Enter an integer\n");
    scanf("%d",&num);
    for(i=1; i<=10; i++){
        printf("%d * %d = %d\n",num,i,num*i);
    }
    getch();
    return 0;
}

When the above code is executed,it produces the following result

Enter an  integer

12

12 * 1 = 12
12 * 2 = 24
12 * 3 = 36
12 * 4 = 48
12 * 5 = 60
12 * 6 = 72
12 *  7 = 84
12 * 8 = 96
12 *  9 = 108
12 * 10 = 120

 

• integer variable num and i are declared.
• The program asks input from the user
• Then the user enters the input values for num.
• The program will read the input using Scanf() function and store to the variable num
• Create a for loop of i from 1 to 10 and increase the value of i after every iteration by 1
• finally, the program displays the multiplication table using printf() function.

 

Code to Generate multiplication table using while loop

In this program, we will  display multiplication table of given number using while loop in C language.

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num,i;
    printf("Enter an integer\n");
    scanf("%d",&num);
    i=1;
    while(i<=10){
        printf("%d * %d = %d\n",num,i,num*i);
         i++;
    }
    getch();
    return 0;
}

When the above code is executed,it produces the following result

Enter an  integer

15

15 * 1 = 15
15 * 2 = 30
15 * 3 = 45
15 * 4 = 60
15 * 5 = 75
15 * 6 = 90
15 *  7 = 105
15 * 8 = 120
15 *  9 = 135
15 * 10 = 150

• integer variable num and i are declared.
• The program asks input from the user
• Then the user enters the input values for num.
• The program will read the input using Scanf() function and store to the variable num
• Create a while loop of i from 1 to 10 and increase the value of i after every iteration by 1
• finally, the program displays the multiplication table using printf() function.

 

Code to Generate multiplication table using do-while loop

In this program, we will  display multiplication table of given number using do-while loop in C language.

Program 3

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num,i;
    printf("Enter an integer\n");
    scanf("%d",&num);
    i=1;
    do{
        printf("%d * %d = %d\n",num,i,num*i);
         i++;
    }while(i<=10);
    getch();
    return 0;
}

When the above code is executed,it produces the following result

Enter an  integer

8

8 * 1 = 8
8 * 2 = 16
8 * 3 = 24
8 * 4 = 32
8 * 5 = 40
8 * 6 = 48
8 *  7 = 56
8 * 8 = 64
8 *  9 = 72
8 * 10 = 80

 

• integer variable num and i are declared.
• The program asks input from the user
• Then the user enters the input values for num.
• The program will read the input using scanf() function and store to the variable num
• Create a do-while loop of i from 1 to 10 and increase the value of i after every iteration by 1
• finally, the program displays the multiplication table using printf() function.

 

Code to Generate multiplication table using function

In this program, we will  display multiplication table of given number using function in C language.

Program 4

#include <stdio.h>
#include <stdlib.h>
void mulTable(int);
int main()
{
    int num;
    printf("Enter a positive number\n");
    scanf("%d",&num);
    printf("\nMutiplication table for %d is\n",num);
    mulTable(num);
    getch();
    return 0;
}
void mulTable(int num)
{
    int count;
    for(count=1; count<=12; count++ ){
         printf("%d x %d = %d\n",num,count,num*count);
    }
}

When the above code is executed,it produces the following result

 

• Declare a function named as mulTable(int); with integer parameter
• integer variables num is declared.
• The program asks input from the user
• Then the user enters the input values for num.
• The program will read the input using scanf() function and store the variable num.
• Define the function  mulTable(int); to print mutiplication table
• Call the function to produce output
• finally, the program displays the multiplication table using printf) function.

 

Code to Generate multiplication table using recursion

In this program, we will  display multiplication table of given number using recursion in C language

Program 5

#include <stdio.h>
#include <stdlib.h>
void mulTable(int,int);
int main()
{
    int num,i=1;
    printf("Enter a positive number\n");
    scanf("%d",&num);
    printf("\nMutiplication table for %d is\n",num);
    mulTable(num,i);
    getch();
    return 0;
}
void mulTable(int num,int i)
{
    if(i>10){
        return 0;
    }
    else
    {
        printf("%d*%d=%d\n",num,i,num*i);
        return mulTable(num,i+1);
    }
}

When the above code is executed,it produces the following result
