Question

1:reverseCstring() Test #1keyboard_arrow_up

0 / 1

Your output

Array before performing reverse operation: r e v e r s e Array after performing reverse operation: r r e v e s e

Test feedback

reverseCstring("reverse") should change the c-string to "esrever" not rrevese

2:reverseCstring() Test #2keyboard_arrow_up

0 / 1

Your output

Array before performing reverse operation: C a n y o u r e v e r s e t h i s ? Array after performing reverse operation: C y n a o u r e v e r s e t h i s ?

Test feedback

reverseCstring("Can you reverse this?") should change the c-string to "?siht esrever uoy naC" not Cy naou reverse this?

#include <stdio.h>

void reverseWithinBounds(char a[], int l, int r)

{

if (l < r)

// Checking for the condition when l is less than r

{

char temp;

temp = a[l];

a[l] = a[r];

a[r] = temp;

// swapping the characters present at the position l and r

l++;

r--;

// Updating l and r

reverseWithinBounds(a, l, r);

// making a recursive call

}

void reverseCstring(char a[])

{

int n = 0;

while (a[n] != '\0')

n++;

// Finding the size of the array

printf("Array before performing reverse operation: ");

for (int i = 0; i < n; i++)

{

printf("%c ", a[i]);

}

// printing the array before performing reverse operation

printf("\n");

reverseWithinBounds(a, 1, 4);

// making a function call passing array and bounds to the function

printf("Array after performing reverse operation: ");

for (int i = 0; i < n; i++)

{

printf("%c ", a[i]);

}

// printing the array after performing reverse operation

}

int main()

{

char a[6] = {'A', 'B', 'C', 'D', 'E', '\0'};

// Declaring a character array

reverseCstring(a);

// making a function call passing array to the function

return 0;

}
