#include

#include

using namespace std;

int main() {

string satr;

int i,k,j;

getline(cin,satr);

string soz[6] ={"puton","output","out","input","one","in"};

for(int i=0;i<6;i++) {

if(satr.find(soz[i])

{

k=satr.find(soz[i]);

j=soz[i].length();

cout<<"Yes";

else cout<<"No"; }

Fayllar bilan ishalsh.

K butun soni va matnli fayl berilgan. Undagi K-nomerdagi satr o`chirilsin. Agar faylda bunday nomerdagi satr mavjud bo`lmasa, u holda fayl o`zgartirishsiz qoldirilsin.

Dastur kodi:

#include

#include

using namespace std;

int main()

{

int K;

cout<<"K = "; cin>>K; cin.ignore();

string fayl;

cout<<"Fayl nomini kiriting: ";

getline(cin, fayl);

ifstream read(fayl.c_str());

string satr[1000];

int n=0;

while(!read.eof())

{

getline(read, satr[n++]);

}

read.close();

ofstream write(fayl.c_str());

for(int i=0; i

if(i!=K-1) write<

write.close();

return 0;

}
