/* C program to find nth odd number */

#include<stdio.h>

int main()

{

    int nOddNumber,oddNum,loop, nthOddNum=0;

    printf("Enter a number: \n");

    scanf("%d",&nOddNumber);

    printf("%dth odd numbers is:\n",nOddNumber);

    for(loop=1,oddNum=1;loop<=nOddNumber;loop=loop+1,oddNum=oddNum+2)

    {

        nthOddNum = oddNum;

    }

    printf("%d",nthOddNum);

    return 0;

}

Output :
