C Program to Find the Sum of Three Numbers

 Program to Find the Sum of Three Numbers (Simple Way)

Algorithm

• Program Start
• Declaring Variables
• Input Three Numbers from User
• Calculating Sum of Three Numbers (sum = x + y + z)
• Displaying the Sum of Three Numbers
• Program End

Program

//C Program to Find the Sum of Three Numbers (Simple Way)

#include<stdio.h>
int main()
{
  //Declaring Four Variables
  
    int x, y, z, sum;           

   printf("Enter Three Numbers : \n");    
   scanf("%d %d %d",&x, &y, &z);     //Input Numbers

  //Calculating Sum of three numbers

   sum = x + y +z;
   printf("Sum of Three Numebers is : %d", sum);    

   return 0;
}

Output

Enter Three Numbers :
10
20
38

Sum of Three Numebers is : 68

C Program to Find the Sum of Three Numbers Using Function

Algorithm

• Program Start
• Declaring variables
• Input three Number
• Calling Function to calculate Sum of three Numbers
• Print the Sum of three Numbers
• Program End

Program

//C Program to Find the Sum of Three Numbers Using Function

#include<stdio.h>
int sum(int, int, int);
int main()
{
 //Declaring Variables
   int x, y, z, s;

  //Input Numbers From User
   printf("Enter Three Numbers : \n");
   scanf("%d %d %d",&x, &y, &z);

 //Calling Function to find the Sum of three numbers
   s = sum(x,y,z);
   printf("Sum of Three Numbers is : %d \n", s);


   return 0;
}
int sum(int a, int b, int c)
{
    return (a+b+c);
}

Output

Enter Three Numbers :
12
18
10
Sum of Three Numbers is : 40

C Program to Find the Sum of Three Numbers Using Array

Algorithm

• Program Start
• Declaring variables
• Input Numbers From the User
• Calculating Sum
• Display the Sum of three Numbers
• Program End

Program

//C Program to Find the Sum of Three Numbers Using Array

#include<stdio.h>
int main()
{ 
  //Declaring  Variables

   int i, sum = 0, a[3]; 
   
   printf("Enter Three Numbers : \n");
   for(i=0; i<3; i++)
   {
    scanf("%d",&a[i]);  //Input Numbers
   }

//Calculating Sum
   for(i=0; i<3;i++)
   {
    sum = sum + a[i];
   }
   printf("Sum of Three Numebers is : %d", sum);
  
 return 0;
}

Output

Enter Three Numbers :
10
29
11
Sum of Three Numbers is : 50
