C Program to find the sum of the elements of a 2-D array.

 C Program to find the sum of the elements of a 2-D array.


    In this example, we will find the sum of the elements of a 2-D array allowing the user to enter the row size and column size according to their requiremnts. 
    Here in the output we have entered a row  size 3 and column size 3.



PROGRAM

#include<stdio.h>
#include<conio.h>
void main()
{
    int a[50][50],r,c,i,j,sum=0;
    printf("Enter the row size and column size of the array :");
    scanf("%d%d",&r,&c);
    printf("Enter the elements of the array : ");
    for(i=0;i<r;i++)
    {
        for(j=0;j<c;j++)
        {
            scanf("%d",&a[i][j]);
        }
    }
    for(i=0;i<r;i++)
    {
        for(j=0;j<c;j++)
        {
            sum=sum+a[i][j];
        }
    }    
    printf("The sum of the elements of the array is = %d",sum);
    getch();
}


OUTPUT

Enter the row size and column size of the array :3

3

Enter the elements of the array : 12

4

65

1

32

73

58

36

45

The sum of the elements of the array is = 326

C program to convert a given temperature value from Fahrenheit to Centigrade and vice versa?

  Write a C program to convert a given temperature value from Fahrenheit to Centigrade and vice versa?          In this example we will learn how to convert a given temperature in Fahrenheit to Centigrade and to convert given  temperature value from Centigrade to Fahrenheit depending on the choice of the user.                To solve this program we should have basic knowledge in c and most importantly a clear concept on : Switch Statement             And we must know the formula of conversion from Fahrenheit to Centigrade(Celsius) and Centigrade(Celsius) to Fahrenheit. Fahrenheit To Centigrade Centigrade To Fahrenheit PROGRAM       #include <stdio.h> #include <conio.h> void   main () {      float   f , c ;      int   ch ;      printf ( "CONVERT" );      printf ( " \n 1. Fahrenheit to Celsius." );      printf ( " \n 2. Celsius to Fahrenheit \n " );      printf ( " \n Enter your choice (1|2):" );      sca

C++ program to define a class circle to represent circles. Add a data member radius to store the radius of a circle. Write member functions area() and perimeter() to compute the area and perimeter of a circle.

  C++ program to define a class circle to represent circles. Add a data member radius to store the radius of a   circle. Write member functions area() and perimeter() to compute the area and perimeter of a circle.     To define a Circle class in C++, we start by declaring the class with the class keyword, followed by the name of the class. In this case, we'll call it Circle . We'll then define a private data member to store the radius of the circle. Here's the code to do that:    class Circle {      private:      double radius;    };          Next, we need to define public member functions that can set and get the value of the radius, as well as calculate the area and perimeter of the circle. Here's the full code for the Circle class: class Circle { private: double radius; public: void setRadius(double r) { radius = r; } double getRadius() { return radius; } double area() { return 3.14159 * r
