Explanation / Answer

Question A)

Write a statement that populates a two-dimensional array named iNums with the values above using shortcut notation. Use the values above.

Answer for this Question is:

Declartion of INums two dimensional arrays is :

int iNums[][]= {{74,3,9},{23,21,62}};

Question B)

Write a statement to display the value stored in iNums[0][0].

Answer for this Question is below:

print "iNums[0][0] index value is", iNums[0][0] = 74

Question C)

Write a statement to display the value stored in iNums[2][2].

Answer for this Question is below:

print "iNums[2][2] index value is", iNums[2][2] = 60

Question D)

Write the statements needed to display the number of rows and columns in the array as follows:

Answer for this Question is below:

Declaration of Rows and Cols and initialise

Rows: 2
Cols: 3

print " Number of Rows and Columns in the given arrays is: ", Rows, Cols

Question E)

Write a statement that adds 5 to the value stored in iNums[1][2].

Answer for this Question is below:

int sum = 0 ;

sum = 5 + iNums[1][2] = 5 + 21 = 26

Question F)

Sum the second value in the first row and the last value in the second row to the variable iSum.

Answer for this Question is below:

Declare :
int iSum = 0;

iSum = iNum[0][1] + iNum[2][2] = 3 + 62 = 65

Question H)

Sum all values in the second row to the variable, iRowTotal.

Answer for this Question is below:

Declare:

int iSum = 0;

iSum = iSum + iNum[1][0] + iNum[1][1] + iNum[1][2] = 23 + 21 +62 = 105
  
print "iSum", iSum; // 23 + 21 + 62 = 105

Question I)

Sum the values in the second column to the variable iColTotal.

Answer for this Question is below:

Declare:

int iSum = 0;

iSum = iSum + iNum[0][1] + iNum[1][1] = 3 + 21 = 24

print "iSum", iSum;
