What does strcmp return if two strings are the same?
If two strings are same then strcmp () returns 0, otherwise, it returns a non-zero value. This function compares strings character by character using ASCII value of the characters. The comparison stops when either end of the string is reached or corresponding characters are not same.
What does zero mean in strcmp ( ) in C?
Zero (0) means that strings are equal. Negative (-1 or any other) means that first string is less. Positive (1 or any other) means that first string is more. Thanks for contributing an answer to Stack Overflow!
Which is address does strg1 point to in strg2?
Now strg1 points to address 2002 and strg2 points to address 3002. This ends the 2nd iteration. In the third iteration both strg1 and strg2 points to the address of character ‘c’ and ‘z’ respectively. So The while condition becomes false and the control breaks out of while loop. if condition following the while loop is checked.
How to search for substrings in strlen in SSE?
The first operand contains a string to search for, the second is a string to search in. The bit mask includes 1 if the substring is found at the corresponding position: After computing the aggregation function, IntRes1 can be complemented, expanded into byte mask or shrinked into index.
Where do strg1 and strg2 point in the loop?
As the condition is true, the statements inside the body of the loop are executed. Now strg1 points to address 2001 and strg2 points to address 3001. This ends the 1st iteration. In the second iteration both strg1 and strg2 points to the address of the character ‘b’. So
How to use strlen, Azaz, and strstr?
Ranges (imm [3:2] = 01). The first operand consists of ranges, for example, “azAZ” means “all characters from a to z and all characters from A to Z”: Equal ordered (imm [3:2] = 11). Substring search (strstr). The first operand contains a string to search for, the second is a string to search in.
