"goto" statement in C Language

 goto statement in C

 The goto statement is a jump statement which is sometimes also referred to as unconditional jump statement. The goto statement can be used to jump from anywhere to anywhere within a function.

C Language में goto स्टेटमेंट एक जम्प स्टेटमेंट है कभी-कभी इसे अनकंडीशनल स्टेटमेंट भी कहते है। C प्रोग्राम में कही से कही भी जम्प करने के लिए goto स्टेटमेंट का प्रयोग करते है।

Syntax 1 – label: . . . goto label;

Syntax 2 - goto label; . . . label:

// C program to print numbers // from 1 to 10 using goto statement #include <stdio.h> #include <conio.h>  void main ( ) { int n = 1; label:             printf("%d\n",n);             n++; if (n <= 10)             goto label; }

//Program to demonstrate //goto statement in C Program #include <stdio.h> #include <conio.h> void main ( ) { int num; clrscr ( ); printf("Enter any number"); scanf("%d",&num); if (num % 2 == 0)             // jump to even             goto even;     else             // jump to odd             goto odd; even:             printf("%d is even", num);             // return if even             getch();             return; odd:             printf("%d is odd", num);             getch(); }

 

Disadvantages of using goto statement:

It makes the program logic very complex.

Use of goto makes the task of analyzing and verifying the correctness of programs very difficult.

Simply avoided using break and cnontinue statements.

C Program to Demonstrate else-if statement

if-else-if in C

In else – if a programmer can make decision among multiple conditions. In C "if statements" are executed from the top down approach. As soon as one of the if is true, the statement associated with if is executed, and the rest of the C else – if is bypassed. If none of the conditions are true, then the final else statement will be executed.

Syntax: 

if (condition)

    statement;

else if (condition)

    statement;

else if (condition)

    statement;

else if (condition)

    statement;

.

.

else

    statement;

C Program to understand the concept of "if-else" statement in C by Satyam Srivastava

If-else Statement

The if-else statement is used to perform two operations for a single condition. The if-else statement is an extension to the if statement using which, we can perform two different operations, i.e., one is for the true condition, and the other is for the false. Here, we must notice that if and else block cannot be executed in same time. The syntax of the if-else statement is given below.

if(condition)

{  

//code to be executed if condition is true  

}

else

{  

//code to be executed if condition is false  

}

C - if statement

An if statement consists of a Boolean expression followed by one or more statements.

Syntax :

The syntax of an if statement in C programming language is −

if (condition)

{

statement(s) will execute only if the boolean expression is true

}

If the Boolean expression evaluates to true, then the block of code inside the 'if' statement will be executed. If the Boolean expression evaluates to false, then the first set of code after the end of the 'if' statement (after the closing curly brace) will be executed.

{

clrscr();

int mo, tm, per;

printf("Enter total Marks\n");

scanf("%d",&tm);
