5. set precision on decimal
#include <iostream>
#include <iomanip> // formatting floating-point numbers with 1 decimal place
using namespace std;
int main()
{
float m1=22, m2=7; // important
cout << fixed << setprecision(3);
cout << " " << m1 << " + " << m2 << " = " << m1 / m2 << endl;
return 0;
}
6. take input and do sun
#include <iostream>

int main()
{
int a, b;
cin >> a >> b;
cout << a + b;
return 0;
}
7. swap numbers
#include <iostream>
using namespace std;
int main()
{
int a, b; // a=5,b=2
cin >> a >> b;
a = a + b; // a=7
b = a - b; // b=5
a = a - b; // a=2
cout << a << b;
return 0;
}
8. date time print
#include <iostream>
#include <iostream>
#include <cmath>
#include <ctime>
using namespace std;
int main()
{
time_t t = time(NULL);
tm *tPtr = localtime(&t);
cout << "\n\n Display the Current Date and Time :\n";
cout << "----------------------------------------\n";
cout << " seconds = " << (tPtr->tm_sec) << endl;
cout << " minutes = " << (tPtr->tm_min) << endl;
cout << " hours = " << (tPtr->tm_hour) << endl;
cout << " day of month = " << (tPtr->tm_mday) << endl;
cout << " month of year = " << (tPtr->tm_mon) + 1 << endl;
cout << " year = " << (tPtr->tm_year) + 1900 << endl;
cout << " weekday = " << (tPtr->tm_wday) << endl;
cout << " day of year = " << (tPtr->tm_yday) << endl;
cout << " daylight savings = " << (tPtr->tm_isdst) << endl;
cout << endl;
cout << endl;
cout << " Current Date: " << (tPtr->tm_mday) << "/" << (tPtr->tm_mon) + 1 << "/" << (tPtr->tm_year) + 1900 << endl;
cout << " Current Time: " << (tPtr->tm_hour) << ":" << (tPtr->tm_min) << ":" << (tPtr->tm_sec) << endl;
cout << endl;
return 0;
}
9. print size of array
#include <iostream>
using namespace std;
int main()
{
int array1[] = {1, 2, 3, 4, 5, 6, 7, 8};
int *eo;
int s1 = sizeof(array1) / sizeof(array1[0]);
cout << s1 << sizeof(array1) << sizeof(array1[0]);
return 0;
}
10. print ASCII values
#include <iostream>
using namespace std;
int main()
{
char sing_ch;
cout << "\n\n Print code (ASCII code / Unicode code etc.) of a given character:\n";
cout << "-----------------------------------------------------------------------\n";
cout << " Input a character: ";
cin >> sing_ch;
cout << " The ASCII value of " << sing_ch << " is: " << (int)sing_ch << endl;
cout << " The character for the ASCII value " << (int)sing_ch << " is: " << (char)((int)sing_ch) << endl;
return 0;
}
11. Reverse a number
#include <iostream>
int main()
{
int n = 102;
int i=0;
while (n > 0)
{
i = (n % 10) + i * 10;
n = n / 10;
}
std::cout << i; // Outputs "201"
return 0;
}
