Write a c program to add two numbers / integers using function..

Note: The same program can be used for adding floating numbers, just we have

to change the function return type,and all variables to float type and

for large numbers declare as long..

PROGRAM:

#include<stdio.h>

#include<conio.h>

int sum(int,int); /*declaring prototype of function*/

void main()

{

int a,b,c;

printf("\n Enter the two numbers : ");

scanf("%d %d",&a,&b); /* taking two numbers as input*/

c = sum(a,b); /* calling function,

*the value returned by the function is stored in c */

printf("\n The sum of two numbers is : %d ",c);

getch();

}

int sum ( int num1,int num2)

{

int result; /* defining variable, its scope lies within function */

result = num1 + num2 ; /*adding two numbers*/

return (result) ; /* returning result */

}

Sample Output: ( using GNU GCC Compiler with Code Blocks IDE )

Enter the two numbers: 10 15

Can you please write a prog on division using functions.

ReplyDeleteHI pavan, for getting division of two numbers using function,

Deletein the above program just change the following

c = division(a,b);

int division( int num1,int num2)

{

int result; /* defining variable, its scope lies within function */

result = num1 / num2 ; /*division of two numbers*/

return (result) ; /* returning result */

}

great explanation

Delete#include

Deleteint div(int,int);

int main(void)

{

int a,b,result;

printf("\nenter the two integers:\n");

scanf("%d%d",&a,&b);

result=div(a,b);

printf("\nthe division of %d and %d is %d",a,b,result);

return 0;

}

int div(int p ,int q)

{

int c1;

if(q==0)

printf("\n UNDEFINED\n");

else

c1=p/q;

return (c1);

}

hi! can you please draw a flowchart of this program, i'll be very grateful, can't find any flowchart of functions anywhere

ReplyDeletehad anyone helped u in it Mr.Sharma?

Deletehmmmm

ReplyDeleteaddition of three num. using function. one should be in main nd others should be in function.. will u help me with this query?

ReplyDelete#include

Delete#include

int total (int, int);

int main()

{

int a, b, c, d, e;

d = 450;

printf("1st number is: %d\n",d);

printf("Now Enter other the two numbers:\n\n");

scanf("%d %d", &a, &b);

c = total(a, b);

e = c + d;

printf("Total of three Numbers is: %d\n",e);

getch();

return 0;

}

int total(int num1, int num2)

{

int result;

result = num1 + num2;

return result;

}

#include #include int sum(int x,int y); //function declaration void main() { int a,b,c; clrscr(); printf("Enter the two numbers:"); scanf("%d%d",&a,&b); c=sum(a,b); //function call printf(" \n the sum of two number is : %d ",c); getch(); } int sum(int x,int y) //function definition { int c; c=x / y; return c; }

ReplyDeletecan any one help mw with finding function prototype with flow charts?

Happy coding ;)

I will like to know how to add to no. Which are declare in function n one function in main in c++

The sum of two numbers is: 25

ReplyDeletepls someone solve it...

ReplyDeleteque-write a c program to create 2 single dimensional array size by store data into the 2nd array.display the data both the erray?

add two numbers with arguments and without

ReplyDeletereturn values .... plz help

Hi, We can also add two numbers using pointers in C.

DeletefirstNumberPointer = &firstNumber;

secondNumberPointer = &secondNumber;

sum = *firstNumberPointer + *secondNumberPointer;

This blog awesome and i learn a lot about programming from here.The best thing about this blog is that you doing from beginning to experts level.

ReplyDeleteLove from

Write function max(), this function find the maximum number between three numbers Write a program that uses this function to allow user enter numbers and print maximum number

ReplyDelete#include

ReplyDeletevoid addition();

void subtraction();

void multiplication();

void division();

Int a,b,choice;

int main ()

Printf("value of a");

Scanf("%d",&a);

Printf("value of b");

Scanf("%d",&b);

printf("please type /n 1 for add/n 2/ for sub/n 3 for mul/n 4 for div/n");

printf("enter your choice");

scanf("%d",&choice);

if(choice==1)

{

void addition()

}

}

{

printf("sub of %d and %d is %d",a,b,(a-b));

}

void muptiplication();

{

printf("mul of %d and %d is %d",a,b,(a*b));

}

void division();

{

printf("div of %d and %d is %d",a,b,(a/b));

}

please tell me how to print the result in main if function is void type

ReplyDeleteHi, In this case, you can use a global variable.

Delete#include

int result; /*global variable*/

int main()

{

int a=10,b=20;

sum(a,b);

printf("\n The sum of two numbers is : %d ",result);

return 0;

}

sum(int num1,int num2)

{

result = num1 + num2 ; /*adding two numbers and storing result in global variable*/

}

I write same in code::block but it's not working

ReplyDeleteEverything worked....plz elaborate use of scanf and printf .....why %d is used....

ReplyDelete%d is used as a format specifier, here is a samll example, go through this link http://cprogramsblog.blogspot.com/2012/07/c-program-for-showing-printf-format.html
