Question

Using while or do while loop: wap to read any integer number and print its multiplication table

Answer/Solution

In this program, we are reading an integer number and printing its multiplication table, we are implementing the program using for, while and do while (through all loops).

Logic

Read an integer number
Take a loop counter and initialize it with 1
Run a loop from 1 to 10
Print the multiplication of input number and loop counter
Increase the loop counter

Complete program using while loop

#include <stdio.h>
int main()
{
	int num; 	/*to store number*/
	int i;	/*loop counter*/
	
	/*Reading the number*/
	printf("Enter an integer number: ");
	scanf("%d",&num);
	
	/*Initialising loop counter*/
	i=1;
	
	/*loop from 1 to 10*/
	while(i<=10){
		printf("%d\n",(num*i));
		i++; /*Increase loop counter*/
	}
	
	return 0;
}

Output

Enter an integer number: 12 
12
24
36
48
60
72
84
96
108
120

Code using do while loop

/*Initialising loop counter*/
i=1;

/*loop from 1 to 10*/
do{
	printf("%d\n",(num*i));
	i++; /*Increase loop counter*/
}while(i<=10);

Code using for loop

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