For loop in a C program, if the condition is missing

it is assumed to be present and taken to the true

it is assumed to be present and taken to be false

execution will be terminated abruptly

What is the maximun number of dimensions an array in C may have?

Theoratically no limit. The only practical limits are memory size and compilers

Size of the array need not be specified, when

Initialization is a part of definition

Choose the correct statements

The number of subscripts determines the dimension of the array

All The elements of the array should be of the same data type and storage class

The array elements need not be of the same storage class

In an array definition. the subscript can be any expression yielding a non-zero integer value

Which of the following statements are correct about the program below? #include<stdio.h> int main() { int size, i; scanf("%d", &size); int arr[size]; for(i=1; i<=size; i++) { scanf("%d", arr[i]); printf("%d", arr[i]); } return 0; }

The code is erroneous since the statement declaring array is invalid.

The code is erroneous since the subscript for array used in for loop is in the range 1 to size.

The code is erroneous since the values of array are getting scanned through the loop.

The code is correct and runs successfully.

Let A be a square matrix of size n x n. Consider the following program. What is the expected output? C = 100 for i = 1 to n do for j = 1 to n do { Temp = A[i][j] + C A[i][j] = A[j][i] A[j][i] = Temp - C } for i = 1 to n do for j = 1 to n do Output(A[i][j]);

Adding 100 to the upper diagonal elements and subtracting 100 from diagonal elements of A
