Can we have better soln and here is my soln?

#1

#include
using namespace std;
char names_input[][10]={“prateek”, “sneha”, “deepak”, “arnav”, “shikha”, “palak”, “utkarsh”, “divyam”, “vidhi”, “sparsh”, “akku”};
char keypad[][5]={"","",“abc”,“def”,“ghi”,“jkl”,“mno”,“pqrs”,“tuv”,“wxyz”};
void generate_strings(char input[],char output[],int i,int j)
{
if(input[i]==’\0’)
{
output[j]=’\0’;
for(int l=0;l<=10;l++)
{
for(int k=0;names_input[l][k]!=’\0’;k++)
{
int m;
int temp=k;
for(m=0;output[m]!=’\0’;m++)
{
if(names_input[l][k]==output[m])
k++;
else
break;
}
if(m==j)
{
cout<<names_input[l]<<endl;
break;
}
else
k=temp;
}
}
return;
}
if(input[i]==‘0’)
generate_strings(input,output,i+1,j);
int t=input[i]-‘0’;
for(int q=0;keypad[t][q]!=’\0’;q++)
{
output[j]=keypad[t][q];
generate_strings(input,output,i+1,j+1);
}
}
int main()
{
char ch[10];
char output[10];
cin>>ch;
generate_strings(ch,output,0,0);
return 0;
}

@namangarg31 you can use the string datatype instead of char to be more space efficient but it wont make much difference
