#include<conio.h>

Void main()
{
int num1, num2, sum, result;
clrscr();
printf("Enter Two Numbers:");

printf("\n The Sum of Two Number is:");
go to sum;
printf("\n This Statement is just after the goto Statement\n");

printf("\n *************************");
sum;
result= num1 + num2;
printf("%d", result);

Answer :

#include<stdio.h>

#include<conio.h>

Void main()

{

int i, sum=0;

for(i=1; i<=20; ++i)

{

if(i%2!=0) continue;

19. Write a Program for the sum of numbers as many user wants?

Answer :

#include<stdio.h>

#include<conio.h>

Void main()

{

int num, sum=0;

char ch;

Read:

printf("Enter the Number:");

scanf("%d", & num);

sum= sum+num;

printf("You Want to Enter More Number, Enter Y");

fflush(stdin);

scanf("%c",&ch);

if(ch == 'y' || ch == 'y')

goto read;

printf("The Sum of N Numbers =%d", sum);

getch();

}

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

printf("\n Press 1 : For Addition");

printf("\n Press 2 : For Substraction");

printf("Enter Your Choice:");

scanf("%d", &ch);

switch(ch)

{

case 1: printf("Addition= %d", a+b);

         break;
