IF statement as String matching can only be done through if statement.

The answer is Java

Pair is used to combine together two values which may be different in type.

Yes it is possible. This is known as Dynamic initialization. The example is given below 

eg: int a = 10, b = 5; int c = a*b; here the variable c is declared and initialized with the value 10*5.

R-value (Read value) of a variable

Old ratio (P, Q and R) = 4 : 3 : 2

New Ratio (P and R) = 5 : 3

Gaining ratio = New ratio - Old ratio 

P's gain = (5/8) - (4/9) = 13/72

R's gain = (3/8) - (2/9) = 11/72

On H's admission :

Old ratio (P and R) = 5 : 3

H is admitted for 3/10 shares

P's sacrifice in favour of H = (3/10) x (3/4) = 9/40 ......(1/2 + 1/4 = 3/4)

R's sacrifice in favour of H = (3/10) x (1/4) = 3/40

New ratio = Old ratio - sacrificing ratio

P's new share = (5/8) - (9/40) = 16/40

R's new share = (3/8) - (3/40) = 12/40

H's share = P's sacrifice + R's sacrifice

= (9/40) + (3/40)

= 12/40

Therefore, new ratio of P, R and H is 16 : 12 : 12 or 4 : 3 : 3

Yes it is possible to declare a variable in between the program as and when the need arise. It is known as dynamic initialisation. 

eg. int x = 10, y = 20;

int z = x*y;

R-value is 33 and L-value is 1001

The correct program is given below.

#include<iostream> 

using namespace std;

int main()

{

int num1, num2, sum; 

Cout<<“Enter two numbers:”;

cin>>num1>>num2;

sum = num1+num2;

Cout<<"sum of numbers are=”<<sum; 

}

Globalisation has hurt our country's development because: firstly, it has led to the annihilation of small producers who face stiff competition from cheaper imports. Secondly, workers no longer have job security and are employed "flexibly". Globalisation is helping India develop on account of the following reasons: firstly, the competition it entails has led to rise in the quality of products in the market. Secondly, it has made available a wider variety of goods in the market, for the buyer to choose from. Now, imported goods are easily available alongside domestic products.

Correct option is B) takes up

Correct option is B) break down

float uses 4 bytes of memory.

Yes. lt is known as Dynamic declaration

char data type 1 uses bytes of memory.

Integer data type uses 4 bytes of memory

Correct option is A) put out

American Standard Code for Information Inter-change

d) special characters can be used

constant word is used for this.

float data type uses 4 bytes of memory

1)P=P+1; 

2) p++;(post increment) 

3) ++p; (pre increment) 

4) p+=1; (short hand in C++)

c) float pi=3.14157

c) const float pi=3.14157

Fundamental data types 

int 

float 

double 

void 

char

Derived data types

array 

function 

pointer 

structure

Integer data type uses Integer data type is 4.

int is the exact data type.

Correct option - (B) getc 

Explanation:-

getc is used to read a character from a file that has been

C Standard Library:

C would have been a tough programming language in absence of the standard library. The standard library in C includes header files and standard functions in these files. Header files are collection of macros, types, functions and constants. Any program that needs those functions has to include these header files. For example, the standard library functions, included in “stdlib.h” header file, are used for number conversions, storage allocation and other functions on the same line. These functions are called utility functions. C does not have any built-in input/output statements as part of its syntax. All I/O operations are carried out through function calls such as printf and scanf. There are many functions that have become standard for I/O operations in C, collectively known as standard I/O library “stdio.h”. Because of this standard inputoutput header file, standard I/O functions can be used on many machines without any change. 

Correct option -(A) library function

Explanation:-

main() is a special function used by C system to tell the computer where the program starts.

Correct option - (B) 2¹⁵-1

Explanation:-

If we use a 16 bit word length, the size of the integer value is limited to the range -2¹⁵ to 2¹⁵-1 

The initial value of P₁ is 2800 which is an integer pointer so new value of P₁ is 2802 after P₁= P₁+1 

The initial value of P₂ is 1411 which is a long integer pointer so new value of P₁ is 1415 after P₂= P₂+1 because long takes 4 bytes of memory.

The initial value of P₃ is 1201 which is a char type pointer so new value of P₃ is 1202 after P₃= P₃+1 

Correct option - (B) malloc

Explanation:-

malloc allocates requested size of bytes and returns a pointer to the first byte of the allocated space. 

Correct option - (C) modulus( )

Explanation:-

modulus( ) function produces the reminder of an integer division.
