![]() ![]() The first word of both string values is equal, and that is “ Good,” but the second part of the string values is not equal. To see if two numeric values are greater than or equal to each other, we use the comparison operator >. Two string values have been stored into two variables. #Perl string compare codeCreate a PERL file with the following code to know the use of the “ eq” operator for comparing string values. The “ eq” operator is used in PERL to find out whether two string values are equal or not. So, “ Both strings are equal.” has been printed in the third output. Both “hello” and “hello” are equal that have been taken in the third execution of the code. By default, the character is guaranteed to match only the beginning of the string, the character only the end (or before the newline at the end), and. For the same reason, “ Hello is less than hello” has been in the second output. So, “ hello is greater than Hello” has been printed in the first output. The character “ h” is greater than the character “ H” based on the ASCII value of these characters. The first input value was “ hello,” and the second input value was “ Hello” in the first execution of the code. # Compare the string variables using 'cmp' operatorĪccording to the following output, the code has been executed three times. # Remove newline from each string variable ![]() The return value of the “cmp” operator will be -1 if the first string is less than the second string. ![]() The return value of the “cmp” operator will be 1 if the first string is greater than the second string. The return value of the “cmp” operator will be 0 if both strings are equal. Next, the output of the “cmp” operator will be stored in a variable. The chomp() function has been used in the code to remove the newline from both string values taken from the user. Two string values will be taken from the user for the comparison. String comparison Programming comparison between float numbers Perl: Search for string on line then compare numbers Hi All, I have a file that I need to be able to find a pattern match on a line, take the number on that line check if its >0.9 or <0.1 and if this is true write the line to output.out file. Create a PERL file with the following code to know the uses of the “cmp” operator in PERL. The “cmp” operator is used for comparing two strings and finding out if the first is less than or equal to, or greater than the second string. Different ways of comparing two strings in PERL have been shown in this tutorial.” Compare Strings Using the “cmp” Operator One way is to use the “ cmp” operator, and another way is to use comparison operators, which are “eq,” “ne,” “lt.” and “gt.” The “ =” operator is used for number comparison only in PERL. “Many options exist in PERL to compare string values. ![]()
