Re: Pls someone help me...

So, you've just started on a programming course, eh? How did I guess.

Break it down into simple steps. Start with a program that prints a line of stars.

Then change it so that it prints a line of n stars where you can specify the value of n (within the program).
Code:

```int n=5; // code that prints a line of n stars```
Then can you think of a way to repeat that line over and over with n increasing from 1 to a maximum value? Hint: you'll probably have used the same statement in printing a line of n stars.

If what I just posted doesn't answer that question, then no, obviously I can't.

Code: CPP

`#include<stdio.h>main(){int x,y,z;for(x=1;x<=40;x+=2){for(y=1;y<=40-x;y+=2){printf(" ");}for(z=1;z<=x;z++){printf("*");}printf("\n");}}`

Re: Pls someone help me...

Good work :)
But, please always post code within [code].....[/code]

And, as you have not mentioned the return type of main(), it's int by default; so remember to add return 0; at the end.

here th no. of lines is :7
Code:

```#include<stdio.h> #include<conio.h> void main() { int m; clrscr(); printf("enter the terms :"); scanf("%d",&m); for(int i=1;i<=n;i++)  {     for(int j=1;j<=n-i;j++)       printf(" ");         for(j=1;j<=i;j++)           printf("* ");       printf("\n"); } getch(); }```

how to make multiplication table using c++?

 xpi0t0s 28Sep2009 19:08

Re: Pls someone help me...

What do you want the program to display?
Can you work out how to display part of that display?
For example a multiplication table might read
1x2=2
2x2=4
3x2=6
Let's leave the difficult part of working out the solution for now, so let's write a program that just displays
1x2=
2x2=
and so on.
Can you work out how to do that?
