#include<iostream>
using namespace std;
int hms_to_sec(int hr,int min, int sec);
int main()
{
int hr,min,sec;


int result =hms_to_sec(hr,min,sec);
cout << "result = " << result;
system("pause");
return 0;
}

int hms_to_sec(int hr,int min, int sec)
{
int seconds =0;
cout << "please enter hr" << endl;
cin >> hr;
cout << "please enter min" << endl;
cin >> min;
cout << "please enter sec" << endl;
cin >> sec;

seconds = (hr*60*60)+(min*60)+sec;
return seconds;

using only #include and #include Write a program in C that will read an input from the user and print it back to the user if it is a palindrome. The string ends when it encounters a whitespace. The input string is at most 30 characters. Assume the string has no spaces and distinguish between and lowercase. So madam is a palindrome, but MadAm is not a palindrome. Use scanf and %s to read the string. Sample Test: Enter a string: madam madam is a palindrome. Enter a string: 09023 09023 is not a palindrome.
