Velma is graduating from Ashford at the end of next year. After she completes her final class, she will reward herself for her h

motikmotik

This question is incomplete because the options are missing; here are the options for this question:

Which of the following is the most effective way for Velma to save money each month?

A. Automatically reroute a portion of her paycheck to her savings account.

B. Manually deposit 10% of her paycheck in her savings account.

C. Pay all of her bills and then place the remaining money in her savings account.

D. Pay all of her bills and then place the remaining money in her piggy bank.

The correct answer to this question is A. Automatically reroute a portion of her paycheck to her savings account.

Explanation:

In this case, Velma needs to consistently save money for her vacation as this guarantees she will have the money for the trip. This means it is ideal every month she contributes consistently to her savings for the vacation.

This can be better be achieved by automatically rerouting a part of her paycheck for this purpose (Option A) because in this way, every month the money for the vacations will increase and the amount of money will be consistent, which means Velma will know beforehand the money she will have for the vacation. Moreover, options such as using a piggy bank or paying the bills and using the rest for her savings, do not guarantee she will contribute to the savings every month, or she will have the money she needs at the end.

Write the following function without using the C++ string class or any functions in the standard library, including strlen(). Yo

dolphi86 [110]

Answer:

The function in C++ is as follows

int chkInd(string str1, string str2){

int lenstr1=0;

while(str1[lenstr1] != '\0'){ lenstr1++; }

int index = 0; int retIndex=0;

for(int i=lenstr1-1;i>=0; i--){

while (str2[index] != '\0'){

if (str1[i] == str2[index]){

retIndex=1;

break; }

else{ retIndex=0; }

index++; }

if (retIndex == 0){ return i; }else{return -1;}}

}

Explanation:

This defines the function

int chkInd(string str1, string str2){

First, the length of str1 is initialized to 0

int lenstr1=0;

The following loop then calculates the length of str1

while(str1[lenstr1] != '\0'){ lenstr1++; }

This initializes the current index and the returned index to 0

int index = 0; int retIndex=0;

This iterates through str1

for(int i=lenstr1-1;i>=0; i--){

This loop is repeated while there are characters in str2

while (str2[index] != '\0'){

If current element of str2 and str1 are the same

if (str1[i] == str2[index]){

Set the returned index to 1

retIndex=1;

Then exit the loop

break; }

If otherwise, set the returned index to 0

else{ retIndex=0; }

Increase index by 1

index++; }

This returns the calculated returned index; if no matching is found, it returns -1

if (retIndex == 0){ return i; }else{return -1;}}

}

The purpose of a method's postcondition is to

anyanavicka [17]

The answer that would best complete the given statement above would be option 5. The purpose of a method's postcondition is to describe the conditions that are true when the method completes. On the other hand, precondition describes the conditions that are true before the method is complete. Hope this helps.
