Ascending Pyramid of Numbers in C

#include < stdio.h >

int main() {

int i,j,rows;

printf(“Enter the number of rows: “);

scanf(“%d”,&rows); for(i=1;i<=rows;++i)

{

for(j=1;j<=i;++j) { printf(“%d “,j);

}

printf(“\n”);

}

return 0;

}

 

Output:

1

1 2

1 2 3

1 2 3 4

1 2 3 4 5

Your name :

So here we go here is the list of the questions.

1.Write a program to add one file into another.
2.Count the number of elements in a linked list and delete the last 3 elements.
3.Write program that counts all occurances of perticular word.
4.Reverse digits of an integer.
5.Write program to read name of person & return the ascii value of it.
6.Write a code to find factorial of any number.
7.Concatenate two linked lists.
8.Test whether the given string is a plaindrome(reads the same in both directions)
9.Find the square root,cube rrot without using the c library function.
10.Write a program to accept file from user and count the vowels in it with or without opening it.
11. Try to produce the output as below:

1
1 2
1 2 3
1 2 3 4
1 2 3 4        
*  *   *
*   *   *   *
*    *   *    *    *
*   *   *   *    *   *

12. Write a program to find the hex values of given number.
13.Write a program to find ASCII value of key typed.
