For Versus While

For Versus While

/*Program 1 --> For loop*/
for (<init - stmnt>;<boolean - expr>;<incr - stmnt>) {
<body-statements>
}
 
/*Program 2 --> While loop*/
<init - stmnt>;
while (<boolean - expr>) {
<body-statements>
<incr-stmnt>
}

Solution :

When the body of a loop contains a “continue” statement, it can significantly affect the behavior of the loop. In your examples, “Program 1” and “Program 2” appear to have different outcomes due to the placement of the “continue” statement:

• In “Program 1,” it seems that the “continue” statement is within a loop that executes three times. In this case, “loop” will be printed three times, and the loop will continue to execute.
• In “Program 2,” it suggests that the “continue” statement is within a loop that lacks an appropriate condition to terminate. As a result, the “continue” statement might cause the loop to run indefinitely, resulting in an infinite loop.

The key takeaway is that the placement and conditions surrounding the “continue” statement within a loop are crucial in determining the loop’s behavior. It can either skip the remaining code in a specific iteration and continue to the next iteration or lead to unintended consequences like an infinite loop if not used carefully.

Example: Using for Loop

Syntax:

 for(initialization ; condition ; increment/decrement)
    {  
        //statement 
    }     

#include <stdio.h>
 
int main()
{
    int  sum=0, i;
    for(i=1;i<=5;i++)
    {
        sum=sum+i;
    }
     
      printf("SUM = %d" , sum);
     
      return 0;
}

Output

SUM = 15

Example: Using While Loop

Syntax

while(condition)
    {  
        //code for execution
    }

// Example:
 
#include<stdio.h>
 
int main()
{
    int no=1, sum=0;
   
    while(no<=5)
    {
        sum=sum+no;
        no++;
    }
         
      printf("SUM = %d" , sum);
 
      return 0;
}

Output

SUM = 15
