Question

Define a method void Swap(char  ch1,char ch2) to interchange the values of arguments ch1 and ch2 . Also, print the characters.

Answer 1

#include <stdio.h>
void Swap(char  *ch1,char *ch2)//we need to take pointer here then only you can able to swap the characters
{
*ch1=*ch1+*ch2-(*ch2=*ch1);
}

int main()
{
    char ch1,ch2;
    printf("enter any two characters");
    scanf("%c %c",&ch1,&ch2);
    Swap(&ch1,&ch2);
    printf("%c,%c\n",ch1,ch2);
        printf("%d,%d\n",ch1,ch2);
    
    

    return 0;
