regex pattern to match the end of a string
(5 answers)
Closed 3 years ago.
I want to detect a string at the end of a pattern using C regex lib.
I'm looking for a string like ".mystring" with the litteral dot.
I expect the following to work :
char * pattern = "[[:alnum:]!--_]+\.(mystring)";
But it doesn't. What am I doing wrong here ?
You need to use $ end of string anchor
char * pattern = "[[:alnum:]!--_]+\.(mystring)$";
Also no need to of capture group here
char * pattern = "[[:alnum:]!--_]+\.mystring$";

Would it be possible to loop through each character in the string, and then place each character into an array?
I'm new to swift, and I'm trying to figure this out. Could someone write a code for this?
It's really simple:
let str = "My String"
let letters = str.characters.map({String($0)})
print(letters)

string comparison inside if condition malfunctioning [duplicate]

Closed 6 years ago.
I am trying to implement an IF STATEMENT
in my C-Server.
read(client_fd,received_data,100);
printf("%s",received_data);
I want to print "ooo" if the received data equals to "test"
if (received_data == "test") {
printf('ooo');
}
?
The above example results in errors. (can't compile)
I don't know much C.
UPDATE :
Now I can compile fine ( after changing 'ooo' to "ooo" )
But although I am sending "test" to it.. if statement is not doing anything i think.
The == doesn't work for const char *.
Use strcmp instead.

LoadRunner web_reg_save_param, ord=all, paramName_count issues

Closed 6 years ago.
I am using the web param function to retreive certain values. I want to get the value of a specific index from the array item and store it in a parameter to be used in a web_link call.
char * tempVal;
web_reg_save_param("dynArray","LB=/EmployeeProfile/","RB=\">","ORD=ALL",LAST);
tempVal = "{dynArray_2}";
There is no error for the above statements but when accessing tempVal it is giving error
vuser_init.c(143): web_link("emp") started [MsgId: MMSG-26355]
vuser_init.c(143): Warning: The string 'tempVal' with parameter delimiters is not a parameter.
vuser_init.c(143): Error -27995: Requested link ("Text={tempVal}") not found [MsgId: MERR-27995]
You have a problem which is C language based. You cannot simply equate two items as you have done.
take a look at the strcpy() function combined with lr_eval_string()
strcpy (destination_C_variable, lr_eval_string( "{LoadRunner_source_variable}" ) );

Convert Swift string to array
(14 answers)
Closed 6 years ago.
I've got a little problem. I want to split a String in an array of characters, where I can work on each character.
For example:
"Hello"
arrayofstring[0] ->H
arrayofstring[1] ->e
arrayofstring[2] ->l
arrayofstring[3] ->l
arrayofstring[4] ->o
I am thankful for every help.
Unless I'm missing something, it's easier than either of the other answers:
let arrayofstring = Array("Hello".characters)
Do something like this:
let string : String = "Hello"
let arrayofstring = string.characters.map { (Character) -> Character in
return Character
}
println(arrayofstring)

I meant, something that we can use this way:
char string1[] = "???, buddy*\0";
char string2[] = "Hey, buddy, hello!\0";
if (like(string1, string2)
puts("strings are similar!");
else
puts("string are different!");
You want to use a regular expression library. See this question for the ANSI library information: Regular expressions in C: examples?
