C language: Enter a positive number less than 1000, output its square root, if not less than 1000 positive, re-enter

Enter a positive number less than zero from the keyboard , which requires the output of its square root (if the square root is not an integer, output its integer portion). Requires that the data be checked for a positive number that is less than zero after it is entered . If not, a re-entry is required.

Solution: Program:

#include <stdio.h>

#include <math.h>

#define M 1000

int main ()

{

int x, y;

printf ("Please enter a positive number less than%d x:", M);

scanf ("%d", &x);

while (X>M)

{

printf ("Input data does not meet the requirements, please re-enter a positive number less than%d x:", M);

scanf ("%d", &x);

y = sqrt (x);

}

y = sqrt (x);

printf (the integer portion of the square root of "%d" is:%d\n ", x, y);

return 0;

}

Result 1:

Please enter a positive number less than + x:Bayi

The integer part of the square root of Bayi is : 9

Result 2:

Please enter a positive number less than + x:

The data entered does not meet the requirements, please re-enter a positive number less than + x:7612

The data entered does not meet the requirements, please re-enter a positive number less than + x:121

The integer part of the square root of the 121 is : One
