⏩ goto Statement in C

🔍 Short Explanation:
The goto statement allows an unconditional jump to a labeled statement within the same function. Use it cautiously as it can make code less readable and harder to maintain.

---

✅ Syntax

goto label;

...

label:
    // code to execute
  

📋 Example: Exiting Nested Loops

#include <stdio.h>

int main() {
    int i, j;

    for (i = 1; i <= 3; i++) {
        for (j = 1; j <= 3; j++) {
            if (i == 2 && j == 2) {
                goto end_loop;  // jump to label
            }
            printf("i=%d, j=%d\\n", i, j);
        }
    }

end_loop:
    printf("Loop exited using goto.\\n");
    return 0;
}
  

🧠 Output:
i=1, j=1
i=1, j=2
i=1, j=3
i=2, j=1
Loop exited using goto.

⚠️ Use with Caution

• Overuse can lead to “spaghetti code”
• Better to use structured control statements when possible
• Sometimes useful for breaking out of deeply nested loops

📌 Summary

The goto statement provides an unconditional jump in the flow of execution within a function. Use it sparingly and thoughtfully.
