Write a recursive function called firstOccurence that will return the position of the first occurence of a character within a string B.) Write a recursive function called sumAscii that will return the sum all of the chars within a string. For B the sum of the chars is their ASCII equivalent value. For instance the character 'A' has a value of 65.

C+ + code is explained below

Explanation:

a - C+ + code:

#include

using namespace std;

#include

int firstOccurence (char * s, char c) / /recursive function

{

static int i;

if (! s[i])

{

return - 1;

}

else

{

if (s[i]==c)

return i;

i++;

firstOccurence (s, c);

} }

int main ()

{

char s[1000], c;

int n;

printf ("Enter the string : "); / /tales input

gets (s);

printf ("Enter character to be searched: "); / /takes input a character to be searched

c=getchar ();

n=firstOccurence (s, c); / /call function

if (n>-1)

printf ("character %c is first occurrence at location:%d ", c, n);

else

printf ("character is not in the string ");

return 0;

}

b - C+ + Code - This program takes a string and display sum of all characters in a string.

#include

using namespace std;

int sumAscii (string s) / /recursive function

{

int sum = 0;

if (s. length () = = 0)

{

exit (0);

}

for (unsigned int i = 0; i < s. size (); i++)

{

sum + = s[i];

}

return sum;

}

int main () / /main function

{

cout << "This word adds up to " << sumAscii ("CAT") << " in ASCII " << endl;

return 0;

}
