RE: Count Number of characters using Pointers

int CharCount(char *str)
{
int count 0;

if (str ! NULL) {
for (; *(str + count) ! ' '; ++count);

}

return count;
}

Here function CharCount will return the number of characters in string.

RE: Count Number of characters using Pointers

const char* A "my name is sam";

char* pPointer A; // set the pointer to point to the first element of the string
int counter 0;

// until the element addressed by pPointer is not null
//traverse the string and increment the counter

while (*pointer ' ')
{
pointer++;
counter++;
}

When while exits counter contains the number of characters in the string.
