Answer:
a. file-naming conventions
Explanation:
File names need to follow certain criteria and constraints. Examples include:
- File names must not start with special symbols.
- File names can consist of letters,digits and special characters such as _.
- File name can contain an extension after a dot sign.
- File names must not be duplicates of an existing file.
Such constraints form part of file-naming conventions.
- file-path represents the complete path to the file in the directory structure.
- disk partition segments a hard disk into multiple volumes.
- file-path starts from the root directory and spans one or more subdirectories to the location of the actual file.
Before cellphones are able to be used to browse the internet, play games, record videos and take photos, its main purpose is similar to a telephone, albeit it is more portable. Early cellphones would not have games for you to play, not would it have emails for you to check, read, and reply to. Though ringtones might seem as an acceptable option, early cellphones would also have many selections or even any for you to choose.
Thus, the best option would be (B) contact list, which is necessary for a cellphone to have since the owner would need the number to be able to make a call.
Answer:
#include <stdio.h>
void interchangeCase(char phrase[],char c){
for(int i=0;phrase[i]!='\0';i++){
if(phrase[i]==c){
if(phrase[i]>='A' && phrase[i]<='Z')
phrase[i]+=32;
else
phrase[i]-=32;
}
}
}
int main(){
char c1[]="Eevee";
interchangeCase(c1,'e');
printf("%s\n",c1);
char c2[]="Eevee";
interchangeCase(c2,'E');
printf("%s\n",c2);
}
Explanation:
- Create a function called interchangeCase that takes the phrase and c as parameters.
- Run a for loop that runs until the end of phrase and check whether the selected character is found or not using an if statement.
- If the character is upper-case alphabet, change it to lower-case alphabet and otherwise do the vice versa.
- Inside the main function, test the program and display the results.
Hi, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.
Answer:
import math
def rectangle(perimeter, area):
l1_1 = (perimeter+math.sqrt((perimeter**2)-(16*area)))/4
l1_2 = (perimeter-math.sqrt((perimeter**2)-(16*area)))/4
l2_1 = area/l1_1
l2_2 = area/l1_2
print(l1_1,l2_1)
print(l1_2,l2_2)
if l1_1.is_integer() and l2_1.is_integer() and l1_1>0 and l2_1>0:
return(int(max(l1_1,l2_1)))
elif l1_2.is_integer() and l2_2.is_integer() and l1_2>0 and l2_2>0:
return(int(max(l1_2,l2_2)))
else:
return(None)
Explanation:
- We import math to make basic operations
- We define the rectangle function that receives perimeter and area
- We calculate one of the sides (l1_1) of the rectangle using the quadratic equation to solve 2h^2 - ph + 2a = 0
- We calculate the second root of the quadratic equation for the same side (l1_2)
- We calculate the second side of the rectangle using the first root on w = a/h
- We calculate the second side of the rectangle using the second root on w= a/h
- We verify that each component of the first result (l1_1, l2_1) is an integer (using the build-in method .is_integer) and greater than 0, if True we return the maximum value between them (using the max function) as w
- If the first pair of sides evaluate to False we check the second root of the equation and if they meet the specification we return the max value
- if all the if statements evaluate to false we return None to indicate that not positive or integer sides were found
Answer:
a.
++score = score + 1
Explanation:
First you have to understand the increment operator;
There are three possible ways to increment the value of variable by 1.
1. <u>post increment</u>
syntax:
name++
it using in expression first then increase the value by 1.
2. <u>Pre increment</u><u> </u>
syntax:
++name
it increase the value by 1 before it using in expression.
3. simple method
name = name +1
In the question,
option 1: ++score = score + 1
it increase the value of score by 2 because their are two increment is used first for (score + 1) and second ++score.
Therefore, the correct option is a.
