memset array bool
Sure! Here is a step-by-step explanation of how to use memset
to set the values of an array of type bool
in C++:
Include the necessary header file:
cpp #include <cstring>
Declare and initialize the array of type
bool
:cpp bool myArray[5];
Set the desired value for all elements of the array using
memset
:cpp memset(myArray, true, sizeof(myArray));
In this example, memset
is used to set all elements of myArray
to true
. The first argument is the pointer to the array myArray
, the second argument is the value to be set (true
in this case), and the third argument is the size of the array in bytes (sizeof(myArray)
).
Note: memset
works by setting each byte of the specified memory block to the specified value. In this case, since bool
is typically represented as 1 byte, setting it to true
will result in setting each byte to a non-zero value.
- The array
myArray
now contains alltrue
values.
cpp
// Printing the array to verify the values
for(int i = 0; i < sizeof(myArray); i++)
{
std::cout << myArray[i] << " ";
}
Output: 1 1 1 1 1
That's it! The memset
function allows you to set the values of an array of type bool
or any other type in C++.
