hey, I need Some help regarding a C program in C language

Question

I am Trying to creat a program using for loop for find the perfect square but I getting set backs.

#include <stdio.h>

//Compiler version gcc 6.3.0

int main()
{
printf("Enter the Square......\n");
int a,b,i;
scanf("%d",&a);
b==a/2;
for( i=1; i>=b; i++)
{
if(a/i==i)
{
printf("The No is perfect square square\n");
break;
}
else
{
printf("The No is not perfect square");
}
}
return 0;
}

This is my code And I wants that if the condition is full fill in the if Block. It should not go to If else blocks.

Answer 1

Totally correct devanille well spotted!

Change from:
if(a/i=i)
to become:
if(i*i==a)

Answer 3

what does that b==a/2 do?

Answer 4

G'day Priyanshu Raj as Cristian Gabriel Mazzulla said:
b==a/2;
That is a check, not an assignment.

When I see = I say "is", when I see == is say "is equal".

you want:
b=a/2;

your for code starts at i=1, runs if i is greater or equal to b (not true, never runs) then increments by i+1.
you want:
for (i=1 ; i<=b ; i++)

I'm not sure about the rest of the math in your code, is that gunna work?

Answer 5

G'day again Priyanshu Raj
I had a go with your code, it was pretty close to perfect. Nicely done!

I added an else if to check for i==b before printing the failure message.
I also changed the if - else if - else so it looped without printing anything when not finished incrementing.

Answer 6

It's Divide the the the square by 2.
