Lecture-14 Break,Continue Keyword , While,Do-while loop in C Programming

Break Keyword

Break keyword are used to stop loop permanently.

💻Example:

//Break Keyword 

#include <stdio.h>

int main() {
    
    for(int i=1;i<=10;i++)
    {
        if(i==5)
        {
            break;
        }
        printf("\n%d",i);
    }
    
    return 0;
}

⚙️ Output :

1
2
3
4

Continue Keyword

continue keyword are used to stop current loop.

💻Example:

//continue Keyword 

#include <stdio.h>

int main() {
    
    for(int i=1;i<=10;i++)
    {
        if(i==5)
        {
            continue;
        }
        printf("\n%d",i);
    }
    
    return 0;
}

⚙️ Output :

1
2
3
4
6
7
8
9
10

While Loop

• Entry Controlled
• Pre-Tested Loop
• if condition will false it will run zero times

Syntax:

while(condion)
{

}

💻Example :

while(condition)
{
#include <stdio.h>

int main() {
    
    int i=0;
    
    while(i<5)
    {
        printf("\n%d",i);
        
        i++;
    }
    return 0;
}

⚙️ Output : 0
1
2
3
4

Do-While Loop

• Exit Controlled
• Post-Tested Loop
• if condition will false it will run ones

Syntax:

do
{
 
}
while(condition);

💻Example:

#include <stdio.h>

int main() {
    
    int i=0;
    
    do
    {
        printf("\n%d",i);
        
        i++;
    }
    
    while(i<5);
    
    return 0;
}

⚙️ Output :

0
