[c-prog] Infinite loop when pass float for int

[ashish sarode]

Hello,

i have following code in C++

#include <iostream>
using namespace std;
int main()
{
 int i;
 while(1)
 {
  cout<<"Enter a number";
  cin>>i;
  if(i==1)
   break;
 }
 return 0;
}

After running this code, if i enter a floting precision value - E.g. 2.3 for i 
then the code goes into infinite loop.

Interestingly if i enter 1.1 or 1.36 for i then the infinite loop doesnt 
encountered - since the break statement is reached.

I have tried it on Visual Studio 6.0. Can anybody tell me the reason?


I did also tried the same code using printf scanf but the same problem occurs 
for this code also - 

Note- this is .c file

#include <stdio.h>
int main()
{
 int i;
 while(1)
 {
  printf("Enter a number");
  scanf ("%d", &i);
  if(i==1)
   break;
 }
 return 0;
}
