C Programming Example

अदला-बदली के सिवा कुछ नहीं है। यह उनके बीच विनिमय करने के लिए 2 नंबर या कुछ का मान हो सकता है। उदाहरण के लिए, नीचे दिए गए उदाहरण पर विचार करें।

•      स्वैप करने से पहले, ए और बी के मूल्य नीचे दिए गए हैं।

     ए = 10
     बी = २०

•      स्वैप करने के बाद, A और B का मान नीचे होगा।

     ए = 20
     बी = १०

Source Code For C Programming Example

#include 
int main()
{
   int A, B, temp;
 
   printf("Please enter the 1st number : ");
   scanf("%d",&A);
   printf("\nPlease enter the 2nd number : ");
   scanf("%d",&B);
 
   printf("\nBefore swapping:\n");
   printf("A - %d \nB - %d", A, B);
 
   temp = A;
   A = B;
   B = temp;
 
   printf("\nAfter swapping:\n");
   printf("A - %d \nB - %d", A, B);
 
   return 0;
}

OUTPUT : -

Please enter the 1st number : 20
Please enter the 2nd number : 30
Before swapping:
A – 20
B – 30
After swapping:
A – 30
B – 20
