  // statement
}
```

Program to write 10 numbers

Program to print even numbers

Program to print sum of first 10 num

To print the value of integer

Sum of even number from 1 to 100

Program to print addition of 1 to N numbers

#include<stdio.h>
#include<conio.h>
void main()
{
      int n,i,sum=0;
      printf("enter a number:")
      scanf("%d",&n);
      i=1;
      
      while(1<=n)
      {
      sum+1=i;
      ++i;
      }
      printf("sum=&d,",sum);
}

Print reverse of a number
Output:

Write a program to print addition of digit

Program to Add Two Integers
#include <stdio.h>  
 int main() 
 {    
 int number1, number2, sum;       
 printf("Enter two integers: ");  
 scanf("%d %d", &number1, &number2);
 // calculating sum    sum = number1 + number2;           
 printf("%d + %d = %d", number1, number2, sum);   
 return 0;
 }

Do While loop
- Do While statement:
  First it execute the statement and at the end it checks the condition.
```
do
{
statement;
}
while(condition);
```

- Print 10 to 1 using Do while loop :
- Print odd number between 1 to n numbers :

For Loop
- FOR LOOP :
  Syntax for Loop
```
for(statement 1; statement 2; statement 3)
{
   //block of code to be executed
}
```
- Print first 1 to 10 numbers using for loop :
