My code is not working. Why?

Question

#include <stdio.h>

int main() {
  float num1;
  double num2;
  int num3;

  printf("Enter a number: ");
  scanf("%f", &num1);
  printf("Enter another number: ");
  scanf("%lf", &num2);
  printf("other one: ");
  scand("%d",  &num3);
  

  printf("num1 = %f\n", num1);
  printf("num2 = %lf", num2);
  printf("\n");
  printf("num3 = %d", num3);

  return 0;
}

Answer 1

you used scand in ur num3 statement its scanf

Answer 2

In line14 :

 scand("%d",  &num3);

u have given scand instead of scanf

Answer 3

{
  float num1;
  double num2;
  int num3;

  printf("Enter a number: ");
  scanf("%f", &num1);
  printf("Enter another number: ");
  scanf("%lf", &num2);
  printf("other one: ");
  scanf("%d",  &num3);

  printf("num1 = %f\n", num1);
  printf("num2 = %lf", num2);
  printf("\n");
  printf("num3 = %d", num3);

  return 0;
}

The code works good , only error was that you wrote scand instead of scanf ...

Otherwise it works perfect , Thank you .

Answer 4

scand("%d",  &num3);

should be

scanf("%d",  &num3);

Answer 5

place scanf inplace of scand

Answer 6

replace sacnd into scanf

Answer 7

Replace scand with scanf in line 13

Answer 8

Replace scand with scanf at 3rd input stage

Answer 9

use cin and cout instead of scanf and printf and calculate seperately

also to use cin and cout add the header file iostream  #include <iostream>

and after  that write:

using namespace std;

Answer 10

13TH LINE scand to scanf

REMOVE THE EXTRA MARK FROM %f

Comments

"REMOVE THE EXTRA MARK FROM %f"

No.

scanf("%lf") is scanning for long float (64 bit), that is double.
scanf("%f") is scanning for floats (32 bit).

He is right to have lf format specifier for doubles.
