Answer:
#include <stdio.h>
int main(void) {
char letterToQuit = '?';
int numPresses = 0;
printf("Press the %c key %d times to quit ", letterToQuit, numPresses);
return 0;}
Explanation:
in print statement %c is replaced by value of variable 'letterToQuit'and %d is replaced by value of variable 'numPresses'
Answer:
int main() {
int _2dArray[32][32];
for (int i = 0; i < 32; i++) {
for (int j = 0; j < 32; j++) {
_2dArray[i][j] = j + i * 32;
}
}
return 0;
}
Explanation:
Here is a generic C/C++ 2d array traversal and main function example. The rest you'll have to figure out based on what kind of app you're making.
Good luck!
A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment
Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :
EMI
RFI
Explanation:
- EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
- During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
- EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
- Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
- The internal circuits of personal computers generate EM fields in the RF range.
Answer:
Following are the code in the PHP Programming Language:
<u>foreach ($country_codes as $code => $name) {
</u>
Explanation:
The following option is true because the Foreach statement only works on the objects and array and this statement is good for accessing the key and value pairs from the array.
So, that's why to print following associative array through echo statement we use the Foreach loop statement with following right condition.
<u>syntax</u>:
foreach (array as value)
{
code or body to execute;
}
