I want to use printf() in my code

Question

#include<iostream>

#include<vector>

#include<string>

#include<stdio.h>

using namespace std;

vector<string>sort_strings(vector<string>strings){

int smallest=0;

for(int i=0;i<strings.size();i++){

 for(int j=i;j<strings.size();j++){

if(strings[j].compare(strings[smallest])<0)

{smallest=j;}}

if(smallest!=i){

swap(strings[i],strings[smallest]);}}

return strings;}

int main(){

vector<string> s={"ISE","BSCE","BMC","BL","EDUC","BACT"};

cout<<" The programs names Before sort:"<<endl;

for(int i=0;i<s.size();i++){

printf()(s[i]);}

vector<string> sorted_strings=sort_strings(s);

cout<<"\n The programs names after sort:"<<endl;

for(int i=0;i<s.size();i++){

printf()(sorted_strings[i]);

}

return 0;

}
I want to print the string matrix using the print function "printf()" or another print function not using "cout"
I tried to do this but errors appeared in the code editor
So that the elements of the matrix appear under each other

thank you very much

Answer 1

Syntax of printf is

printf("...", …);

So, you need to write something like this:

printf("%s", sorted_strings[i]);

thank you very much
but I wrote
#include<iostream>

#include<vector>

#include<string>

#include<stdio.h>

using namespace std;

vector<string>sort_strings(vector<string>strings){

int smallest=0;

for(int i=0;i<strings.size();i++){

 for(int j=i;j<strings.size();j++){

if(strings[j].compare(strings[smallest])<0)

{smallest=j;}}

if(smallest!=i){

swap(strings[i],strings[smallest]);}}

return strings;}

int main(){

vector<string> s={"ISE","BSCE","BMC","BL","EDUC","BACT"};

cout<<" The programs names Before sort:"<<endl;

for(int i=0;i<s.size();i++){

printf("%s", sorted_strings[i]);}

vector<string> sorted_strings=sort_strings(s);

cout<<"\n The programs names after sort:"<<endl;

for(int i=0;i<s.size();i++){

printf("%s", sorted_strings[i]);

}

return 0;

}
and this error appeares
main.cpp:37:14: error: ‘sorted_strings’ was not declared in this scope

I wrote ...sorted_strings[i].. fo example. You shoud use your own vector name. In your programm it named sort_strings. So use it instead of  sorted_strings
