Textbook Question
Chapter 6.3, Problem 28STE
Consider the following code (and assume that it is embedded in a complete and correct
char next;
int count = 0;
cout << “Enter a line of input:\n”;
cin >> next;
while (next != ‘\n’)
{ if ((count % 2) == 0)
cout << next;
count++;
cin >> next;
}
If the dialogue begins as follows, what will be the next line of output?
Enter a line of input:
0 1 2 3 4 5 6 7 8 9 10 11

#include <stdio.h>void cubeByReference( int *nPtr ); // function prototypeint main( void ){ int number = 5; // initialize number printf("The original value of number is %d", number ); // pass address of number to cubeByReference cubeByReference( &number ); printf("\nThe new value of number is %d\n", number );} // end main
void cubeByReference( int *nPtr ){ *nPtr = *nPtr* *nPtr* *nPtr;}
passing argument by reference -
We modify the code above
1- define a second argument (example "int number2 = 9") and a pointer to it
2- define a second function (addByReference) that adds number2 to number - passing both arguments by reference
3- print-out the result (that is in number)
Upload the output and .c code
#include <stdio.h>int main(){int d;int s[20],i, r, p, lg=0,m;char c;printf("Enter number of salesman(max 20): ");scanf("%d", &d);for(i=0; i<d; i++){ printf("\n salesman %d sales: ");scanf("%d", &s[i]);}for(i=0; i<d; i++){for(r=i+1; j<d; r++){if(s[i] > s[r]){p= s[i];s[i] = s[r];s[j] = p;}}}printf("\nsalesman lowest to highest: ");for(i=0; i<d; i++){printf("%d\t", s[i]);}for(i=0;i<m;i++){printf("\n highest sales: %d ",lg);if(lg<=s[i])lg=s[i];break;}getch();}
>>>
the upper part output should be like this
enter number of salesman (max 20): 5
salesman 1 500
salesman 2 300
salesman 3 1000
salesman 4 200
salesman 5 1000
in the lower part the lowest to highest the output should become like this
salesman 4 200
salesman 2 300
salesman 1 500
salesman 3 1000
salesman 5 1000
highest total sales : 2000
2. Test Scores
File: test_scores.py
Write pseudocode for the main() part of a program that asks the user to enter 4 test scores between 0 and 100, then displays a JCU grade for each score and also the average test score.
When you have written the pseudocode for main, implement your solution in Python code and test it with a range of meaningful data.
Remember that we've done the JCU grades question before, so copy your function from that practical code file.
Sample Output
Score: 3
Score: 50.5
Score: 66
Score: 100
Score 3.0, which is N
Score 50.5, which is P
Score 66.0, which is C
Score 100.0, which is HD
The average score was 54.875
Enhancements
When you have that working...
We asked for 4 scores. Have a look at your code... did you use 4 as a numeric literal or a constant?Change 4 to 3... Did you have to change the program in more than one place?If so, then you've missed one of the things we've taught...As a strong guideline: if you need to use the same literal more than once, you…

All values more than four standard deviations away from the computed average are to be displayed and dropped from any further calculation, and a new average and standard deviation should be computed and displayed.arrow_forward#include <stdio.h>int main(){int d;int s[20],i, j, p, lg=0,m,t=0;char c;printf("Enter number of sale: ");scanf("%d", &d);for(i=0; i<d; i++){ printf("\n sales %d sales: ",i+1);scanf("%d", &s[i]);}for(i=0; i<d; i++){for(j=i+1; j<d; j++){if(s[i] > s[j]){p= s[i];s[i] = s[j];s[j] = p;}}}printf("\n sales lowest to highest: ");for(i=0; i<d; i++){printf("\nsales %d ", s[i]);}printf("\n highest: %d ",t);getch();} it should be: highest : 2000arrow_forwardCode Simulation – Identify the error/mistake or output in the code fragment below: CODE FRAGMENT IDENTIFIED ERROR/MISTAKE/OUTPUT tinclude 1. using namespace std; void multiply(int x, int y) { return x * y; } int main () cout ng namespace std; t multiply (int x, int y) int product{ x * y }; t main() cout « multiply (4) using namespace std; int add (int x, int y, int z) { return x + v + z:arrow_forwardSolve arithmetic expressions in MIPS assemblyUsing the MIPS arithmetic operations covered so far, a program can be created to solve equations.
