how to make a program that will make an output of a triangle figure composed of astirisks using C++.

[xpi0t0s]

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).

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.

can u teach me how to make a figure of triangle composed of astirisks by using loopings?

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

#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");
}
}

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.

the coding is written for a simple floyd triangle looking like below!

here th no. of lines is :7

#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();
}

thank u

how to make multiplication table using c++?

[xpi0t0s]

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?
