Here, a vector of datatype is converted into strings, and then stacked in string vector
Elaborate
velvet creek
```cpp
std::vector<int> int_vector = {1, 2, -2};
std::vector<char*> char...
Look at the beginning of the code
Just change that depending on what numbers you need
Yep 🙃
Do you mean you want to cast an int vector into a char vector ?
Like
{1,5,-2} -> {“1”, “5”, “-2”}
Wait be right back
Are you french?
Ah alright, because we would communicate better if we spoke the same language natively
Anyways
velvet creek
{1,5,-2} -> {“1”, “5”, “-2”}
Is this the plan?
Ohh you mean one string containing all the numbers?
Not familiar with string library in C++ but i can do that in C
And ye
In C is better than C++
Lets be honest C++ sometimes look messy
Dont worry, almost every C code is valid C++ code 😛
Im on phone right now
Please wait
@shadow trout
like this ?
the output is on the right side
Lemme rewrite in C++ then use sprintf_s
#include <iostream>
#include <cstdio>
#include <vector>
int main() {
std::vector<int> int_vector = {1, 2, -2};
std::vector<char> char_array;
for (int i = 0; i < int_vector.size(); ++i) {
char temp[20];
sprintf_s(temp, 20, "%d", int_vector[i]);
for (int j = 0; temp[j] != '\0'; ++j) {
char_array.push_back(temp[j]);
}
if (i < int_vector.size() - 1) {
char_array.push_back(' ');
}
}
std::cout << char_array.data() << std::endl;
return 0;
} ```I gotta go

sprintf in c++ 💀
#include <string>
#include <iostream>
#include <vector>
#include <sstream>
template<typename T>
std::string to_string(std::vector<T> const& v){
std::stringstream ss {};
for(T const& e : v){
ss << e << ' ';
}
std::string s {ss.str()};
s.resize(s.size() - 1);
return s;
}
int main(){
std::vector<int> arr {1, 2, 3};
std::cout << to_string(arr) << '\n';
return 0;
}
gcc main**.c** -o main
velvet creek
wait but it is
look down, on the left side
topaz aspen
```cpp
#include <iostream>
#include <cstdio>
#include <vector>
int main() {
...
this is c++
velvet creek
it does not contain sprintf
velvet creek
Lemme rewrite in C++ then use sprintf_s
