C program to find nth odd number. Take a number as input.
Sol.
Input = 5
Output = 9 //nth odd positive number = 2*n-1
First three odd numbers are 1, 3, 5, 7, 9.
/* 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 :
