Describe a string reversal algorithm. Write the difference between a [ ] [ ] and **a.
String Reversal Algorithm:
strrevers()
{
char str[50];
char rev[50];
int i=-1,j=0;
printf("Enter any string : ");
gets(str);
while(str[++i]!='\0')
while(i>=0)
rev[j++] = str[--i];
rev[j]='\0';
printf("Reverse of string is : %s",rev);
}
Difference between a [ ] [ ] and **a:
a[ ][ ] is represent two dimensional array.
**a represent pointer to pointer.
