C character processing: Assign a specified character from one string to another string using the substr function to extract substrings.
Basic usage: substr (original string, start position, number of characters to be extracted).
For example, if you enter a piece of text "a little fox refuses to be kept in captivity", str1 and copy the little fox to another string, str2substr(str1,5,6), it will be "little fox".

scanf("%c",&s[i]);
This statement asks you to enter the character *
for(i=0;i<7;i++)
printf("%c",s[i]);
Here is the output of the characters you entered.
The second and third floors are wrong, and you can directly assign an initial value to the array when you run the program.
I don't think what you know is whether it's a character or a string.
The C format input and output are single characters.
The input and output of the S format is a string.
Because you are above an array of literal meanings, the input and output are all strings, and the %c format is to give individual characters to the array in turn, and the output is also a single output.
-
If you use an array of characters, you will use a loop to assign each character array unit to another character array unit, and you must be wrong to use numbers directly to assign values like this.
-
Arrays cannot be assigned directly, and pointers can be used.
-
Values cannot be assigned directly.
to strcpy(str,arg);
Of course, STR should be longer than ARG, otherwise it would still be a mistake.
-
Assign values with pointers, or character by character.
-
This shouldn't be difficult, you can choose to decompose the string you want to write, put it in an array, and then put another character into the stringbuffer and add it in a for loop. That should do the trick.

public static void main(string args)
The result is: AAB
abcabcd
abcdeabcdef
abcdefg
abcdefgh
abcdefghi
abcdefghij
abcdefghijk
abcdefghijkl

Two steps, one is read and one is written.
If you don't explain the rules, you can only say that you can find them according to your rules first, and use the substirng method to get them out. Then spell it into the target string.

I don't know what language you are.
Add a space ...... in between
C has a function called strcat(str1,str2);
What it does is connect str2 to str1.
If you want to have a space in between, strcat(string1," ");strcat(string1,string);
Two sentences are sufficient.

Brother, this can be solved with an array. Convert the content of string 1 into an array, give the key value of the dot key, and replace the key value of string 2 after that, no function is required, just a simple array replacement!
-
It will be fine with regular patterns.
Study hard.
-
string str = "abcd";Initial string string st ="bwer";another string char c = ;
boolean flag = false;
for (int i = 0; i < i++)
-
string a = "a";
string b = "b";
a = b;
Thus the value of b is assigned to a.

It can be done very quickly by using the method of columns.
Select all of them. On the menu bar, Data--Column--Fixed Column--Click on the right side of "1202-", and an arrow mark will automatically appear - Done.
Disaggregate the results again.
Data--Column--Separator--Other--Enter a quotation mark in the space on the right--Next--"Column Data Format"Click "Text"--Done.

Assuming your data is in column A, you can enter the following formula in B1 and drop it down.
mid(a1,find("-",a1)+1,find("""",a1)-find("-",a1)-1)
-
You can use the mid function to extract a string of characters.
MIDs are used to return a specific number of characters in a text string that start at a specified position, as specified by the user.
The function MID always counts each character, whether single or double byte, by 1.
Syntax: mid(text, start num, num chars).
Parameters: The mid function syntax has the following parameters:
text required. Contains the text string from which you want to extract characters.
start num is required. The position of the first character in the text to be extracted. The first character in the text has a start num of 1, and so on.
num chars required. Specify the number of characters you want the mid to return from the text.
Description: If start num is greater than the text length, mid returns empty text ()."")。
If start num is less than the length of the text, but start num plus num chars exceeds the length of the text, the mid returns only up to the end of the text.
If start num is less than 1, mid returns an error value of value!.
If num chars is negative, mid returns an error value of value!.
If num bytes is negative, midb returns an error value of value!.
Example: Data"fluid flow "Suppose in cell A1.
mid(a2,1,5) The 5 characters in the string above it, starting with the first character (fluid).
mid(a2,7,20) is the 20 characters in the string above, starting with the seventh character (flow).
mid(a2,20,5) returns an empty text () because the position of the first character to be extracted is greater than the length of the string
-
Columns can be used directly.
You can also use the mid function.
Do it by your train of thought.
