As we know that wave of sound is a mechanical wave and its speed is given by
v = (γRT/M)
whereas the wave of light is an electromagnetic wave and its speed is given by
c = (1/εoμo)
So speed of sound depends on temperature of air but speed of light doesn't.

Program to input any number and display number of odd numbers in it;
#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
#include<string.h>
int main() {
int i, number, num1, num2=0, num3, num4 =0, rem, rem1, rem2, rev = 0;
printf("Enter your number ==> ");
scanf("%d", &number);
num1 = number;
while(num1 != 0) {
rem = num1%10;
rem1 = rem%2;
if (rem1 != 0) {
num2 = num2*10 + rem;
}
num1 /= 10;
}
num3 = num2;
while (num2 != 0) {
