### 16. Design numbers tringle pyramid

Q. Write a program to generate a following numbers triangle:(Where user entered number through keyboard, for example if num=5)

 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1

Ans.
/*c program for number triangle pyramid*/
#include<stdio.h>
#include<conio.h>
int main()
{
int num,r=1,c,sp;
printf("Enter loop repeat number(rows):");
scanf("%d",&num);
for(; num>=1; num--,r++)
{
for(sp=r; sp>1; sp--)
printf(" ");
for(c=1; c<=num; c++)
printf("%d",c);
printf("\n");
}
getch();
return 0;
}
/****************OUTPUT***********
Enter loop repeat number(rows): 5

 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1

********************************/

1. how can i make it the output like this?

1 2 3 4 5
2 3 4 5
3 4 5
4 5
5

that position is not right im seeking for \ like this position

2. Hi Emann, code is written below :
for (int i = 1; i <= 5; i++)
{
for (int k = 1; k <= 5; k++)
{
for (int j = k; j <= 5; j++)

printf("%d", j);

printf("\n");
}

1. i think this is easier
#include
main()
{
int i,j;
for(i=1;i<=5;i++)
{
for(j=i;j<=5;j++)
printf("%d",j);
printf("\n");
}
}

3. 12345
-1234
--123
---12
----1

#include
int main()
{
int i,j;
for(i=1; i<=5; i++)
{
for(j=1;j<i;j++)
{
printf("-");
}
for(j=1;j<=6-i;j++)
{

printf("%d",j);

}
printf("\n");

}

return 0;
}
