C - break and continue

-

 Break and Continue:

Break Vs Continue

breakcontinue

A break can appear in both switch and loop (for, while, do) statements.

A continue can appear only in loop (for, while, do) statements.

A break causes the switch or loop statements to terminate the moment it is executed. Loop or switch ends abruptly when break is encountered.

A continue doesn't terminate the loop, it causes the loop to go to the next iteration. All iterations of the loop are executed even if continue is encountered. The continue statement is used to skip statements in the loop that appear after the continue.

The break statement can be used in both switch and loop statements.

The continue statement can appear only in loops. You will get an error if this appears in switch statement.

When a break statement is encountered, it terminates the block and gets the control out of the switch or loop.

When a continue statement is encountered, it gets the control to the next iteration of the loop.

A break causes the innermost enclosing loop or switch to be exited immediately.

A continue inside a loop nested within a switch causes the next loop iteration.


Break statement(break):  

Sometimes it becomes necessary to come out of the loop even before loop condition becomes false then break statement is used. Break statement is used inside loop and switch statements. It cause immediate exit from that loop in which it appears and it is generally written with condition. It is written with the keyword as break. When break statement is encountered loop is terminated and control is transferred to the statement, immediately after loop or situation where we want to jump out of the loop instantly without waiting to get back to conditional state. 

When break is encountered inside any loop, control automatically passes to the first statement after the loop. This break statement is usually associated with if statement. 

Example : 

void main() 

{ 

int j=0; 

for(j=0;j<6;j++) 

if(j==4) 

break; 

} 

Output: 0 1 2 3

Continue statement (key word continue): 

Continue statement is used for continuing next iteration of loop after skipping some statement of loop. When it encountered control automatically passes through the beginning of the loop. It is usually associated with the if statement. It is useful when we want to continue the program without executing any part of the program. 
The difference between break and continue is, when the break encountered loop is terminated and it transfer to the next statement and when continue is encounter control come back to the beginning position. 
In while and do while loop after continue statement control transfer to the test condition and then loop continue where as in, for loop after continue control transferred to the updating expression and condition is tested. 
Example:- 
void main() 
{ 
int n; 
for(n=2; n<=9; n++) 
{ 
if(n==4) 
continue; 
printf(“%d”, n); 
 }
 }
 Printf(“out of loop”); 
} 
Output: 2 3 5 6 7 8 9 out of loop

C - character set, identifiers, keywords

 character set, identifiers, keywords  Character set:  A character denotes any alphabet, digit or special symbol used to represent information. Valid alphabets, numbers and special symbols allowed in C are The alphabets, numbers and special symbols when properly combined form constants, variables and keywords. Identifiers:   Identifiers are user defined word used to name of entities like variables, arrays, functions, structures etc. Rules for naming identifiers are:  1) name should only consists of alphabets (both upper and lower case), digits and underscore (_) sign. 2) first characters should be alphabet or underscore  3) name should not be a keyword  4) since C is a case sensitive, the upper case and lower case considered differently, for example code, Code, CODE etc. are different identifiers.    5) identifiers are generally given in some meaningful name such as value, net_salary, age, data etc. An identifier name may be long, s...

C - Constants and Variables

 Constants And Variable Constants: Constant is a any value that cannot be changed during program execution. In C, any number, single character, or character string is known as a constant. A constant is an entity that doesn’t change whereas a variable is an entity that may change. For example, the number 50 represents a constant integer value. The character string "Programming in C is fun." is an example of a constant character string. C constants can be divided into two major categories:  Primary Constants  Secondary Constants  These constants are further categorized as    Numeric constant   Character constant   String constant Numeric constant:   Numeric constant consists of digits. It required minimum size of 2 bytes and max 4 bytes. It may be positive or negative but by default sign is always positive. No comma or space is allowed within the numeric constant and it must have at least 1 digit. The allowable range for integer const...

C - Loops

-
 Loops in C: Loop:-it is a block of statement that performs set of instructions. In loops Repeating particular portion of the program either a specified number of time or until a particular no of condition is being satisfied.  There are three types of loops in c  1.While loop  2.do while loop  3.for loop   While loop: Syntax:-  while(condition)  {  Statement 1;  Statement 2;  }  Or  while(test condition)  Statement;  The test condition may be any expression .when we want to do something a fixed no of times but not known about the number of iteration, in a program then while loop is used.  Here first condition is checked if, it is true body of the loop is executed else, If condition is false control will be come out of loop.  Example:-  /* wap to print 5 times welcome to C” */   #include  <stdio.h> void main()  {  int p=1;  While(p<=5)  {  printf(“Welcome ...
