Q. Write a C program to print the following number triangle/pyramid program:
1
12
123
1234
123
12
1
Ans.
/*c program for number triangle*/
#include<stdio.h>
int main()
{
int num,n,r,c,z;
printf("Enter max. number : ");
scanf("%d", &num);
for(r=1; r<=num; r++)
{
for(c=1; c<=r; c++)
printf("%d",c);
printf("\n");
}
for(r=1; r<num; r++)
{
for(c=num,z=1; c>r; c--,z++)
printf("%d",z);
printf("\n");
}
getch();
return 0;
}
The output of above program would be:
1
12
123
1234
123
12
