The phrases "or 1=1" and "or ''=''" are typical examples used to manipulate an SQL WHERE clause into evaluating as true.
Consequently, if you type in <span>' or ''=' as your password, you can authenticate if the query would be:
</span><span>select username,pass from users where username='you' and password='' or ''='<span>' limit 0,1;</span></span>
The banking system that poses greater risk of vulnerabilities is the one with ten branches dispersed across California, where data resides on a central mainframe located in San Francisco. If the branches do not share data across the network, the risk of hacking is reduced. However, with a network setup, both data sharing and centralized storage increase exposure to unauthorized access.
Answer:
The decimal representation of 101₂² from base 2 equals 25 in base 10.
Explanation:
To derive the decimal equivalent of 101₂²;
101₂ × 101₂ results in 101₂ + 0₂ + 10100₂.
In this expression, we observe that the '2' in the hundred's place must be converted to '0' while carrying over '1' to the thousand's position, leading to;
101₂ + 0₂ + 10100₂ = 11001₂.
This shows that;
101₂² = 11001₂.
Next, we convert the outcome of squaring the base 2 number, 11001₂, into base 10 through the following method;
Converting 11001₂ to base 10 results in;
1 × 2⁴ + 1 × 2³ + 0 × 2² + 0 × 2¹ + 1 × 2⁰.
The calculation yields;
16 + 8 + 0 + 0 + 1 = 25₁₀.
Answer:
Below is the explanation for the C code.
Explanation:
#include <stdio.h>
#include <stdbool.h>
int main(void) {
int userNum;
bool isPositive;
bool isEven;
scanf("%d", &userNum);
isPositive = (userNum > 0);
isEven = ((userNum % 2) == 0);
if(isPositive && isEven){
printf("Positive even number");
}
else if(isPositive &&!isEven){
printf("Positive number");
}
else{
printf("Not a positive number");
}
printf("\n");
return 0;
}
