Question

Write a C program code for the scenerio below:

An important device carried up to the International Space Station on the last scheduled flight of space shuttle Endeavor was the Alpha Magnetic Spectrometer (AMS-02). As explained by NASA, the AMS is a particle physics detector, searching for antimatter and dark matter and also measuring cosmic rays.

The name strangelets refers to three types of quarks (named u, d or s) which have been discovered experimentally to make up matter, but which are not known to exist in matter on Earth. Write a while-loop that sums up valid numbers ​of d quarks entered by a user from the keyboard.

Specific details are:

* Assume the numbers of d quarks have been recorded as integers. Repeatedly prompt the user to enter a number of observed d quarks, one integer value at a time, and read them in.

* Sum up only the valid values. Occasionally bad data occurs in the space environment, and we don't want invalid data added to the sum.

* Valid values for d quarks observed are defined to be those equal to or greater than 0.

* The user should be instructed to enter the sentinel value of -1111 in order to mark the end of input values.

After all values are entered and the valid ones are added, the total sum ​of all the d quarks should be displayed.

Extra Challenge: Also compute and display the average of the values entered.

Answer 1

//defining the required standard libraries

#include<stdio.h>

//here is the start of main method

void main(){

//Initializing the variables

int i,sum=0,temp,count=0;

float avg;

//Asking the user for input for entering into while loop

printf("enter the input value\n");

scanf("%d",&temp);

while(temp != -1111){

//break condition here is if user enters -1111 we have to terminate the program

if(temp > 0){

//adding only valid integers

sum = sum + temp;

}

//Incresing count for getting number of samples

count = count + 1;

printf("Enter the input value\n");

scanf("%d",&temp);

}

//computing the average

avg = sum/count;

//printing the results

printf("The sum of valid ones are %d\n",sum);

printf("the average is %f\n",avg);

}

below is the ouput of the program.
