Weird output when using merge() function in Standard template library in c++

Question

// merge.cpp // merges two containers into a third #include #include //for merge() using namespace std; int src1[] = { 2, 3, 4, 6, 8 }; int src2[] = { 1, 3, 5 }; int dest[8]; int main() { //merge src1 and src2 into dest merge(src1, src1+5, src2, src2+3, dest); for(int j=0; j<8; j++) //display dest cout << dest[j] << ' '; cout << endl; return 0; } this is the code that I typed and what I expected was a sorted merged array, but the output came out to be : 1210537622105376321053763210537642105376521053766210537682105376 I varied the data, rechecked the syntax but every thing is fine , I think JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

In c++ this is a character ' ' (single quotation marks) and this is a string " " (double quotation marks). Avoid to use single quotation marks for more than one character as it is implementation defined. Fix cout << dest[j] << ' '; to cout << dest[j] << ' '; // remove one whitespace or cout << dest[j] << " "; // change to string A multi-character character constant is interpreted as integer. In your case ' ' is 2105376. With g++ and clang++ ' ' is translated to 8224 = 256 * ' ' + ' '. In your example either you forgot one whitespace or your compiler translates with a different method: 2105376 = 256 * 256 * ' ' + 256 * ' '+ ' ' Enable and read compiler warnings. This was the first thing the compiler told me. :13:24: warning: multi-character character constant [-Wmultichar]
