Program or Solution

					    
							
#include<stdio.h>
int main()
{
	int n,i,j;
	printf("Enter a number:");
	scanf("%d",&n);
	printf("First %d odd numbers are:\n",n);
	for(j=1,i=1;j<=n;i=i+2,j++)
	{
		printf("%d ",i);
	}
	return 0;
}
					    
					

Program Explanation

Instruction(s) inside the for block{} are executed repeatedly till the second expression (j<=n) is true.

Here i and j are initialized to 1 and i is incremented by 2 and j is incremented by 1.

for each iteration, instructions inside the for block are executed unless j becomes greater than n.

so value of i (1,3,5,7.....) (n odd numbers) in each iteration will be printed using printf statement.
