Practical C Programming

How to do it…

1. Enter a string to assign to the str string variable as follows:

printf("Enter a string: ");scanf("%s", str);

2. Set a pointer to point at the string, as demonstrated in the following code. The pointer will point at the memory address of the string's first character:

ptr1=str;

3. Find the length of the string by initializing an n variable to 1. Set a while loop to execute when the pointer reaches the null character of the string as follows:

n=1;while(*ptr1 !='\0'){

4. Inside the while loop, the following actions will be performed:

• The pointer is moved one character forward.
• The value of the n variable is incremented by 1:

ptr1++;n++;

5. The pointer will be at the null character, so move the pointer one step back to make it point ...
