Calculating Sum of Number of elements

Q. Write a C program to accept the number of elements to be insert from the user and calculate these elements sum.

For example:

if user enter no. of elements : 5
then he/she should enter elements value as:
Enter 1 element/number : 2
Enter 2 element/number : 7
Enter 3 element/number : 1
Enter 4 element/number : 10
Enter 5 element/number : 50
Result will be : 
Sum of elements/numbers : 70

Ans.

/*c program for entered number of elements and calculate the sum*/
#include<stdio.h>
int main()
{
 int num,arr[20],i,sum=0;
 //arr[20] value of changeable as big value

Star-Zero Nested Pattern

Q. Write a C program to print the following star-zero nested pattern pyramid as:

*000*000*
0*00*00*0
00*0*0*00
000***000

Ans.

How to make above star-zero nested pattern:

*000*000*
0*00*00*0
00*0*0*00
000***000

In above star-zero nested pattern, there are 4 loops(each loop have different color), so before you making above pyramid, you should make first individual each loop, after making all loop, join them.
That's done.

/*c program for star-zero nested pattern pyramid*/
#include<stdio.h>
int main()
{
