C Graphics Programming

This C Graphics tutorials is for those who want to learn fundamentals of Graphics programming, without any prior knowledge of graphics. This tutorials contains many fundamental graphics program like drawing of various geometrical shapes, use of mathematical function in drawing

curves, coloring an object with different colors, patterns and simple animation programs. This tutorial will provide you an overview of computer graphics and it's fundamentals.

Graphics programming in C using Turbo C provides a nostalgic journey for those who started their programming journey in the DOS era. Turbo C was a popular integrated development environment (IDE) that included a graphics library for simple graphics programming. In this tutorial, we'll explore the basics of C graphics programming using Turbo C, covering topics such as setting up the environment, drawing shapes, handling input, and creating animations.

C Program to Display Current Date and Time

In this program, to get current time and print it in human readable string after converting it into local time we are using two functions defined in time.h header file time() and ctime().

Write a program to find the an element occurring odd number of times in an array.
How to find the only element occurring odd number of times.

C Program to Divide a String into Two Equal Strings

Here is a C program to divide a string in two equal sub strings. Given a string of length L, we have to split this string into two equal sub-strings.

If L is even, then length of the sub-strings will be L/2 and L/2.
If L is off, the length of sub-strings will be L/2 and (L/2)+1

For Example:
Input : "Internet" Output : "Inte" and "rnet"

Algorithm for split a string in two equal sub strings.
Let inputString be the string entered by user and leftHalf and rightHalf are two output sub-strings.

Find length of the string using strlen function. Let it be L.

Find the mid index of input string. (mid = L/2)

Copy characters of inputString from index 0 to mid to leftHalf.

Copy characters of inputString from index mid+1 to L-1 to rightHalf.

C program to split a string into two equal strings

In this program, we will first read a string as input from user using gets function. Then we find the length of input string(L) using strlen function of string.h header file. Now, we will create two sub-strings as explained above and print it on screen.

#include<stdio.h>
#include<string.h>

int main() {

    char inputString[100], leftHalf[100], rightHalf[100];
    int length, mid, i, k;
 
    printf("Enter a string\n");
    gets(inputString);

    length = strlen(inputString);
 
    mid = length/2;
    
    for(i = 0; i < mid; i++) {
        leftHalf[i]= inputString[i];
    }
    leftHalf[i] = '\0';
 
    for(i = mid, k = 0; i <= length; i++, k++) {
        rightHalf[k]= inputString[i];
    }
 
    printf("Left half : %s\n",leftHalf);
    printf("Right half : %s\n",rightHalf);

    return 0;
}

Output

Enter a string
TECHCRASHCOURSE
Left half : TECHCRA
Right half : SHCOURSE
