When to use this block?¶

This block is used to do string processing available in C programming.

How does this block work?¶

The following functions are available in this block,

sprintf¶

Sends formatted output to a string pointed to. It will take the inputs and put it in a single string in the format user has specified.

sscanf¶

Reads formatted input from a string.

strlen¶

Calculate the length of the string.

strcmp¶

Compares the two strings provided. This function return values that are as follows,

1. if Return value < 0 then it indicates str1 is less than str2.
2. if Return value > 0 then it indicates str2 is less than str1.
3. if Return value = 0 then it indicates str1 is equal to str2.

strncmp¶

Parameters,

1. S1 = This is the first string to be compared.
2. S2 = This is the second string to be compared.
3. Num = the maximum number of characters to be compared.

This function return values that are as follows,

1. if Return value < 0 then it indicates str1 is less than str2.
2. if Return value > 0 then it indicates str2 is less than str1.
3. if Return value = 0 then it indicates str1 is equal to str2.

strextract¶

This function extracts the string between begin delimiter and end delimiter.
