50 C Programming Beginner And Basic Code Practice 25 Code Snippets (Part - 1) - GraphCodeX

1.Hello World

    #include <stdio.h>
    #include <conio.h>
    
    void main() {
      printf("Hello, World!\n");
      getch();
    }

Classic C Programming: Hello, World! The "Hello World" program is a traditional and essential starting point for beginners in C programming. It may seem simple, but it lays the groundwork for understanding the basics of programming. Here's why:

2.Printing An Integer

    #include <stdio.h>
    #include <conio.h>
    
    void main() {
    int number = 42;  
      printf("The integer value is: %d\n", number);
      getch();
    }

3.Adding Two Numbers

    #include <stdio.h>
    #include <conio.h>
        void main() {
        int a=15, b=15, c;
        c=a+b;
        printf("The sum of %d and %d is: %d\n", a, b, c);
        getch();
}

4.User Input Adding Two Numbers

    #include <stdio.h>
    #include <conio.h>
        void main() {
        int a=15, b=15, c;
        printf("Enter The First Number: ");
        scanf("%d", &a);
        printf("Enter the second number: ");
        scanf("%d", &b);
        c = a + b;
        printf("The sum of %d and %d is: %d\n", a, b, c);
        getch();
}

5.Multiply Floating Point Numbers

    #include <stdio.h>
    #include <conio.h>
        void main() {
        int a=20, b=20;
        float c=a*b;
        printf("%f\n", c);
        getch();
}

6.Input User Multiply Floating Point Numbers

    #include <stdio.h>
    #include <conio.h>
        void main() {
        int a, b, c;
        float c=a*b;
        printf("Enter The First Number: ");
        scanf("%f", &a);
        printf("Enter The First Number: ");
        scanf("%f", &b);
        printf("The sum of %d and %d is: %d\n", a, b, c);
        getch();
}

7.Find ASCII Value

    #include <stdio.h>
    #include <conio.h>
        void main() {
        char c;
        printf("Enter A Character: ");
        scanf("%c", &c);  
        printf("ASCII Value Of %c = %d", c, c);
        getch();
}

8.Swap Two Numbers

    #include <stdio.h>
    #include <conio.h>
        void main() {
        int a, b, c;
        printf("Enter the first number: ");
     scanf("%d", &a);
     printf("Enter the second number: ");
     scanf("%d", &b);
     printf("Before swapping: a = %d, b = %d\n", a, b);
     c = a;
     a = b;
     b = c;
     printf("After swapping: a = %d, b = %d\n", a, b);
     getch();
}
