Write a program to check if a number is prime or not.

 //program to check if a number is prime or not. //number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7) // 0 and 1 are not prime numbers. // 2 is the only even prime number. #include<stdio.h> int main() {     int n , a;          printf("enter any number\n");          scanf("%d", &n);          for(int i=1; i<=n; i++){ /*for loop is executed until the i value is equal to i*/ if(i%n==0){ a++; /* a will get increment if  i%n=0 */ } } if(a==2){ printf("n is a prime number"); }          else{         printf("n is not a prime number"); }          return 0; } output : enter any number 5 n is not a prime number -------------------------------- Process exited after 8.33 seconds with return value 0 Press any key to continue . .

program to (keep taking number as input from user until user enters a number which is multiple of 5.)

 //keep taking number as input  from user until user enters a number which is multiple of 5. #include<stdio.h> int main() { int n; do{ printf("enter any number="); scanf("%d", &n); printf("%d\n", n); if(n % 5 == 0){ break; } } while(1); printf("you have entered multiple of 5 "); return 0; } output : enter any number=1 1 enter any number=2 2 enter any number=4 4 enter any number=5 5 you have entered multiple of 5 -------------------------------- Process exited after 5.066 seconds with return value 0 Press any key to continue . .

write a program to print the numbers from 0 to n, if n is given by user.

 //program to print the numbers from 0 to n, if n is given by user. #include<stdio.h> int main() { int i=0; int n; printf("enter any number :\n"); scanf("%d", &n); while(i <= n){ printf("%d\n", i); i++; } return 0; } Output : enter  any number : 15 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 -------------------------------- Process exited after 5.739 seconds with return value 0 Press any key to continue . . .
