Program that prints multiplication table of a number (multiplicand and multiplier input by the user)

Problem

Create a program that prints the multiplication table of a number entered by the user (user enter x and y and your program will print the table of x upto y). The table should get displayed in the following form.
2* 1 = 2
2* 2 = 4

Solution - Code

#include<stdio.h>
int main()
{
 int x,y,i;
 printf("Enter x and y: ");
 scanf("%d%d",&x,&y);
 i=1;
 while(i<=y)
 {
  printf("%d*%d=%d\n",x,i,x*i);
  i = i + 1;
 }
 system("pause");
 return 0;

ask user to input starting number and ending number with incremental number and display the numbers between them

Problem

write a program which prompts the user for 3 inputs (shown below - determines how and what to count). The user’s answers should be stored in variables. Your counting program should make use of the for loop.

• Ask the user to enter beginning number to start counting from
• Ask the user to enter ending number to stop counting at
• and also ask the user to enter the incremental number

Solution - Code

#include<stdio.h>
int main()
{
 int i,x,y,z;
 printf("Enter beginning and ending number: ");
 scanf("%d%d",&x,&z);
 printf("Enter increment = ");
 scanf("%d",&y);
 for(i=x;i<=z;i=i+y)
 {
  printf("%d\n",i);
 }
 system("pause");
 return 0;
