Question

lings Review View No Spacing) しHeading 1 CNIT105- INLAB08 Due: By the end of the lab session Objectives: Parallel Arrays Sequential Search Named Constant: Define a named constant, SIZE-20 for size of array Write the code in the main function to do the following tasks 1. Declare an array to store up to 20 scores- whole numbers 2. Partially fill the arrays in a loop- use score -1 to end the data entry 3. Display the number of entries in the array 4. Write a loop to display array score to the screen. 5. Compute the average score - display it to the screen. 6. Use sequential search to display all the scores 70. a. Inform the user if search fails. 7, Use sequential search to find the unique score 100. a. Inform the user if search fails.

Answer 1

you didnt specify the language so I am doing it using c. if you want it in other language comment I will upload it in that language.

<-----------------------------------------------------marks.c------------------------------------------------------------------------------------------>

#include<stdio.h>

//declaring constant int SIZE =20

const int SIZE = 20;

int main(){

//declaring require variables

int marks[SIZE]; //marks array

int data; //data to take input from user and assign it to marks[SIZE] ARRAY

int i; //iterative variable

int no_of_entries=0;//variable for countint total entries into array

int sum = 0; //variable to track the sum of all elements in the array

float average; //float for calculating average value

//using loop to take input from user

for(i = 0;i<SIZE;i++){

printf("Enter Student's Score : ");

scanf("%d",&data);

marks[i]=data;

//checking data weather it is -1 or not using if condition

if(data==-1){

//breaking the loop if enter data is -1

break;

}

//calculating sum at the time of input

sum = sum + data;

//incrementing no of entries

no_of_entries++;

}

//printing no of entries

printf("\nNo of Entries = %d\n",no_of_entries);

//loop for printing scores

printf(" Score\n *****************************\n");

for(i=0;i<no_of_entries;i++){

printf(" %d\n",marks[i]);

}

//calculating average and printing average upto 2 values after decimal

average = (float)sum/(float)no_of_entries;

printf("\n The average score is %0.2f\n",average);

//printing scores greater than or equal to 70 using sequential search

printf("\n Scores >= 70 are : \n");

for(i=0;i<no_of_entries;i++){

if(marks[i]>= 70)

printf(" %d\n",marks[i]);

}

//finding 100 score using seqential search

int score_found_flag = 0;

for(i=0;i<no_of_entries;i++){

if(marks[i]==100){

printf("\n Student with score=100 was found\n");

score_found_flag = 1;

break;

}

}

//if we did find 100 the if condition will execute

if(!score_found_flag){

printf("\n Student with score=100 was not found\n");

}

}

same input as shown in the question image
