Which of the following is a valid way to declare and initialize an integer array to store the ages of 50 students?

Name the method of search depicted in the below picture:

Define a class to accept values into 4x4 array and find and display the sum of each row.

Example:

A[][]={{1,2,3,4},{5,6,7,8},{1,3,5,7},{2,5,3,1}}

Output:

sum of row 1 = 10 (1+2+3+4)
sum of row 2 = 26 (5+6+7+8)
sum of row 3 = 16 (1+3+5+7)
sum of row 4 = 11 (2+5+3+1)

Consider the following program segment and answer the questions given below:

int x[][] = {{2,4,5,6}, {5,7,8,1}, {34, 1, 10, 9}};

(a) What is the position of 34?

(b) What is the result of x[2][3] + x[1][2]?
