C String concatenation using memcpy not appending


C String concatenation using memcpy not appending

wish help you to fix your issue You are repeatedly copying the null terminator at the end of test. sizeof tbuf is 5.
So all the C standard library functions will ignore all the other concatenants.

I wish this help you I have resource strings : ,
Question : Is string concatenation possible in layout file?
code :
<com.whatever.ConcatenateTextView
    android:text="@string/whatever"
    custom:concatenate="@string/second_string"/>
ImageView mImageOne;
TextDrawable d = new TextDrawable(this);
d.setText("SAMPLE TEXT\nLINE TWO");
d.setTextAlign(Layout.Alignment.ALIGN_CENTER);

mImageOne.setImageDrawable(d);

seems to work fine I'm trying to extract values out of an array and concatenate all the values in one string like the following
code :
recipe.ingredients = tags.flatMap { $0.titleLabel?.text }.joinWithSeparator(" ")

Hope this helps So from what I can tell there are 3 problems here:
Values are primarily prepended to the string. For each value a character is appended. If only one value is present, nothing should be appended or prepended. With 2 or more items, the 0th item is handled differently:
code :
int length = propositions.size();
if (length == 0) {
    main = "";
} else {
    StringBuilder sb = new StringBuilder();
    int nestingDepth = 0;
    // Reverse loop, ignoring 0th element due to special case
    for (int i = length - 1; i > 0; i--) {
        sb.append("|(").append(propositions.get(i)).append(',');
        nestingDepth++;
    }
    // Append last element due to special casing
    sb.append(propositions.get(0));
    for (int i = 0; i < nestingDepth; i++) {
        sb.append(')');
    }

    main = sb.toString();
}

fixed the issue. Will look into that further From the Go language spec:
code :
package main

import (
    "fmt"
    "strconv"
)

func main() {
    a := 4 
    b := "The value of a is "

    fmt.Println(b + strconv.Itoa(a))
}

hope this fix your issue With the list-comprehension, three if-conditions, one function call and global. The second version only uses two if-conditions.
You can reduce to one if-condition inside the loop, to get even faster results:
code :
def string_compression(string):
    string = iter(string)
    char = next(string)
    result = [char]
    counter = 1
    for new_char in string:
        if new_char != char:
            # if char doesn't equal previous char, append counter and new char then reset counter
            result.append(str(counter))
            result.append(new_char)
            counter = 0
            char = new_char
        counter += 1 # inc counter every pass
    result.append(str(counter)) # append final count of latest char
    return ''.join(result)
