Need code


Try the Following Five Programs

1) Program for Prime Number Generation

#include <stdio.h>
main()
{
int n,i=1,j,c;
clrscr();
printf("Enter Number Of Terms
");
printf("Prime Numbers Are Follwing
");
scanf("%d",&n);
while(i<=n)
{
c=0;
for(j=1;j<=i;j++)
{
if(i%j==0)
c++;
}
if(c==2)
printf("%d ",i)
i++;
}
getch();
}
--------------------------------------------------------------------------------------------------------------------------------------------------

2)Program for finding the prime numbers

#include <stdio.h>
#include <conio.h>
void main()
{
int n,m,k,i,max;
char c;
clrscr();
repeat: max=0;
k=2;

else
goto try1;
if (k < n/2)
goto again;
else
printf("%d",n);
printf(" ");
try1: n=n+1;
k=2;
}
fflush(stdin);
printf ("

Do you want to continue?(y/n):- ");
scanf("%c",&c);
if (c=='y')
goto repeat;
getch();

}
---------------------------------------------------------------------------------------------------------------------------------------------------

3)
  1. #include <stdio.h>
  2. int main(void) {
  3. int n,
  4. lcv,
  5. flag; /* flag initially is 1 and becomes 0 if we determine that n
  6. is not a prime */
  7. printf("Enter value of N > ");

4)

#include<stdio.h>

#include<conio.h>

void main()

{

int n,i,c=0;

clrscr();

printf("enter the number:");

scanf("%d",&n);

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