Solution:
long power(int abc, int pow)
{
if (pow)
{
return (abc * power(abc, pow - 1));
}
return 1;
}Question 3
Write a C Program to print Binary Equivalent of an Integer using Recursion
Solution:
int binary_conversion(int xy)
{
if (xy == 0)
{
return 0;
}
else
{
return (xy % 2) + 10 * binary_conversion(xy / 2);
}
}Question 4
Write a C Program to reverse a given word using function. e.g. INDIA should be printed as AIDNI
Solution:
int sz;
sz = strlen(str1);
reverse(str1, 0, sz - 1);
printf("The string after reversing is: %s", str1);
return 0;
}
void reverse(char str1[], int index, int size)
{
char temp;
temp = str1[index];
str1[index] = str1[size - index];
str1[size - index] = temp;
if (index == size / 2)
