Values after swapping: a= 20, b= 10 2) Swapping two numbers without using third variable We can also swap two numbers without using the third variable. This method saves computation space hence is more effective. Let, variableacontains first value, variablebcontains second value. Step 1: a ...
Raw Blame // Swap two integers without using third variable #include<stdio.h> int main() { int a, b; printf("Enter two no :\n"); scanf("%d%d",&a,&b); a = a^b; b = a^b; a= a^b; printf("After swapping value of a and b : %d,%d",a,b); return 0; }Fo...

The logic toswap the two arrays without using a third variableis as follows ? for(i=0;i<size;i++){first[i]=first[i]+sec[i];sec[i]=first[i]-sec[i];first[i]=first[i]-sec[i];} Program The following C program swaps two arrays without using a temporary variable. It reads the...
Suppose you have two variables x and y and you want to swap their values. The usual way to do this is using another temporary variable: temp = x; x = y; y = temp; However, the interchange of two variables can be done without the temp variable: ...
The simplest method to swap two variables is to use a third temporary variable : define swap(a, b) temp := a a := b b := temp Pictorial Presentation: Sample Solution: C Code: #include<stdio.h>voidswap(int*,int*);intmain(){intn1,n2;printf("\n\n Function : swap two numbers u...
You can swap variables having integers without the use of additional memory (like a temporary array or variable). The following example swaps the variablesaandbusing the addition+and difference-arithmetic operators: let a = 1; let b = 2; ...
