💻 Practical Program

📘 Step Learning

We can have multiple initializations in the for loop as shown below. for (i=1,j=1;i<10 && j<10; i++, j++)

💻 Program Code

#include <stdio.h>
int main()
{
   int i,j;
   for (i=1,j=1 ; i<3 || j<5; i++,j++)
   {
	printf("%d, %d\n",i ,j);
   }
   return 0;
}

🖥 Program Output

📘 Explanation

Multiple initialization inside for Loop in C

We can have multiple initialization in the for loop as shown below.

for (i=1,j=1;i<10 && j<10; i++, j++)

What’s the difference between above for loop and a simple for loop?
1. It is initializing two variables. Note: both are separated by comma (,).
2. It has two test conditions joined together using AND (&&) logical operator. Note: You cannot use multiple test conditions separated by comma, you must use logical operator such as && or || to join conditions.
3. It has two variables in increment part. Note: Should be separated by comma.

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
