In this tutorial you will learn about the C program to print date and its application with practical example.
In this tutorial, we will learn to find current system date day and time using C programming language. There are many different method to find system date and time in C programming.
Prerequisites
Before starting with this tutorial we assume that you are best aware of the following C programming topics:
- C library.
- Operators.
- in-built functions.
- Basic input/output.
- Basic C programming.
Often we need to work on current date and time in our program.
C program to print date
Here we write a program, in which we want to check current date and time to given date and time to confirm the user age .Now we will see how to write a C program to print current date and time.

#include<stdio.h> #include<time.h> int main() { time_t t; // datatype of ISO library time(&t); // standard time fucntion printf("Current system Day Month date ,time and year = %s" , ctime(&t)); // current day and time return 0; } |
Output
Here how the above program works:
Here we have taken The time_t datatype it is a data type from the C ISO library which is define to store system’s time value.
time() function will returns the system date and time.
With the help of function ctime() it will returns a string that shows the local time based on t (parameter) timer. This ctime() function is defined in time.h header file.we just need to include inbuilt header file in our program and function define within header file just need call them and that’s it our will call system day and all..
that will give the current day, month , date , time and year..
