Question

q : explain the code for a beginner in c what each line do

Question 2. The following code defines an array size that sums elements of the defined array through the loop.

1. Analyze the following code, and demonstrate the type of error if found?
2. What we can do to make this code function correctly ?

#include <stdio.h>

#define A 10

int main(int argc, char** argv) {

int Total = 0;

int numbers[A];

for (int i=0; i < A; i++)

numbers[i] = i+1;

int i =0;

while (i<=A){

   Total += numbers[i];

   i++;

}

printf("Total =%d\n", Total);

return 0;

}

Answer 1

Code:

#include <stdio.h>

// we are defining constant value that can't changed
// the value of the A is 10 through the whole program
#define A 10

// define a main funcion
int main(int argc, char** argv) {

// this is integer variable Total = 0
int Total = 0;

// declare a array of size 10 since the value of A = 10
int numbers[A];

// using for loop iterate it 10 times
for (int i=0; i < A; i++)

// store the values inside the array
numbers[i] = i+1;
// end of for

// initialize the i value to 0
int i =0;

// using while loop iterate the while loop 10 times
while (i<A){
  
// sum the array elements
Total += numbers[i];

// increment the i value everytime
i++;

}

// print the result finally.
printf("Total = %d\n", Total);

return 0;
