Why it is not giving the output?? What is the error in it??

Question

#include <stdio.h>

int main() {
printf("***DECIMAL TO BINARY***\n");
int num ,i=0;
int arr[10];
printf("Enter a number\n");
scanf("%d",&num);
for(int i=0; i>=0; i++){
arr[i] = num % 2;
num = num / 2;
}
for(int j= i-1;j>=0; j--){
printf ("Binary = %d",arr[j]);
}
return 0;
}

Answer 1

for(int i=0; i>=0 ; i++) //this is infinite loop..
Condition i>=0 always true.. So never stops...

Answer 2

Check my profile rupali i correct your own in my code bits decimal to binary

Answer 3

Didn't effective sir 😑

Answer 4

Yes sir it's working now!!
Thanks to you😄😄

Answer 5

Instead for loop condition write num>0,
And don't intilize again int I =0, rupali
just put i=0
so
for(i=0 ; num>0; i++)

Or use

while(num>0)
{
i++;
...
..}
Remaining works..

Answer 6

//do check this after, your try only..

#include <stdio.h>

int main() {
printf("***DECIMAL TO BINARY***\n");
int num ,i=0;
int arr[10];
printf("Enter a number\n");
scanf("%d",&num);
printf("Number = %d, \n in binary :", num) ;
for( i=0; num>0; i++){
arr[i] = num % 2;
num = num / 2;
}
for(int j= i-1;j>=0; j--){
printf (" %d",arr[j]);
}
return 0;
}
