Q1. Difference betweenn local and global variables.


BASIS FOR COMPARISONLOCAL VARIABLEGLOBAL VARIABLE
DeclarationVariables are declared inside a function.Variables are declared outside any function.
ScopeWithin a function, inside which they are declared.Throughout the program.
AccessAccessed only by the statements, inside a function in which they are declared.Accessed by any statement in the entire program.
LifeCreated when the function block is entered and destroyed upon exit.Remain in existence for the entire time your program is executing.
StorageLocal variables are stored on the stack, unless specified.Stored on a fixed location decided by a compiler.

Q2. Wap a program to search INDIA from string

LOVEINDIA and display it on screen.



#include <string.h>
#include <stdio.h>
  
int main()
{
    // Take any two strings
    char s1[] = "LOVEINDIA";
    char s2[] = "INDIA";
    char* p;
  
    // Find first occurence of s2 in s1
    p = strstr(s1, s2);
  
    // Prints the result
    if (p) {
        printf("String found\n");
        printf("First occurrence of string '%s' in '%s' is '%s'", s2, s1, p);
    } else
        printf("String not found\n");
  
    return 0;
}

What are Keywords in C?

What are Keywords in C? Keywords are preserved words that have special meaning in C language. The meaning of C language keywords has already been described to the C compiler. These meaning cannot be changed. Thus, keywords cannot be used as variable names because that would try to change the existing meaning of the keyword, which is not allowed.(Don't worry if you do not know what variables are, you will soon understand.) There are total 32 keywords in C language. auto double int struct break else long switch case enum register typedef const extern return union char float short unsigned continue for signed volatile default goto sizeof void do if static while What are Identifiers? In C language identifiers are the names given to variables, constants, functions and user-define data. These identifier are defined against a set of rules. Rules for an Identifier An Identifier can only have alphanumeric characters(a-z , A-Z , 0-9) and underscore( _ ). The fir...

Features of C language

Image
Features of C language It is a robust language with rich set of built-in functions and operators that can be used to write any complex program. The C compiler combines the capabilities of an assembly language with features of a high-level language. Programs Written in C are efficient and fast. This is due to its variety of data type and powerful operators. It is many time faster than BASIC. C is highly portable this means that programs once written can be run on another machines with little or no modification. Another important feature of C program, is its ability to extend itself. A C program is basically a collection of functions that are supported by C library. We can also create our own function and add it to C library. C language is the most widely used language in operating systems and embedded system development today.

Structure in C

Introduction to Structure Structure is a user-defined datatype in C language which allows us to combine data of different types together. Structure helps to construct a complex data type which is more meaningful. It is somewhat similar to an Array, but an array holds data of similar type only. But structure on the other hand, can store data of any type, which is practical more useful. For example:  If I have to write a program to store Student information, which will have Student's name, age, branch, permanent address, father's name etc, which included string values, integer values etc, how can I use arrays for this problem, I will require something which can hold data of different types together. In structure, data is stored in form of  records . Defining a structure struct  keyword is used to define a structure.  struct  defines a new data type which is a collection of primary and derived datatypes. Syntax: struct [ structure_tag ] { //me...
