Help in counting elements in array

#include<iostream>
#include <string>
#include <fstream>
using namespace std;

struct sndex{
char code[4];
int freq;
};


int main(){

sndex sx[15];


strcpy (sx[0].code, &quot;S100&quot;
//sx[0].code[4], '\0';
sx[0].freq = 1;

strcpy (sx[1].code, &quot;S100&quot;
//sx[1].code[4], '\0';
sx[1].freq = 1;

strcpy (sx[2].code , &quot;S120&quot;
// sx[2].code[4], '\0';
sx[2].freq = 1;

strcpy (sx[3].code , &quot;S130&quot;
// sx[3].code[4], '\0';
sx[3].freq = 1;

strcpy (sx[4].code , &quot;S120&quot;
// sx[4].code[4], '\0';
sx[4].freq = 1;

strcpy (sx[5].code , &quot;S130&quot;
// sx[5].code[4], '\0';
sx[5].freq = 1;

strcpy (sx[6].code , &quot;S140&quot;
// sx[6].code[4], '\0';
sx[6].freq = 1;

strcpy ( sx[7].code , &quot;S130&quot;
// sx[7].code[4], '\0';
sx[7].freq = 1;

strcpy (sx[8].code , &quot;S150&quot;
//sx[8].code[4], '\0';
sx[8].freq = 1;

strcpy (sx[9].code , &quot;S140&quot;
// sx[9].code[4], '\0';
sx[9].freq = 1;
strcpy (sx[10].code , &quot;S150&quot;
//sx[8].code[4], '\0';
sx[10].freq = 1;

cout << &quot;CODE FREQ&quot; << endl;
cout << &quot;============================&quot; << endl;

/*
for(int i =0; i<10; i++){

cout << sx.code << &quot; &quot; << sx.freq << endl;


}

*/

int N = 11;

int m=0;
for(int i=0;i<N;i++){
for(int j=i+1;j<N;j++) {
//if(sx==sx[j])sx[j]=' ';
if(!strcmp(sx.code,sx[j].code)){
sx[j].freq+=1;
cout << sx[j].code << &quot; &quot; << sx[j].freq<<endl;
}
}
}
return 0;

}


In the above code I wanted to count no of structs.
Someone give me a clue....

Thanks in advance.

There 2 ways u could get the count
1. Use a count var and whenever u set any value to a struct, increment it.
2.
//Initialize the var
for(int i =0; i<15; i++)
{
strcpy(sx.code,&quot;&quot;
}
//add the values
.
.
.
//Since the max num of structs in Arr are 15
for(i =0; i<15; i++)
{
if(strcmp(sx.code,&quot;&quot < 0)
break;
}
//the value of i will give you the number of structs that uv
//set

Thanks for the responce.
But I wanted to count the structures containing same values.
The result must look like this:

CODE FREQ
=========================
S100 2
S120 2
S130 3
S140 2
S150 2

Thanks in advance....

#include<iostream>
#include <string>
#include <fstream>
using namespace std;

struct sndex{
char code[4];
int freq;
};

struct sndex sx[15];

void addDatEntry(char* param);

void main(){


//Since the max num of structs in Arr are 15
for(int i =0; i<15; i++)
{
strcpy(sx.code,&quot;\0&quot;
}

addDatEntry(&quot;s100&quot;
addDatEntry(&quot;s100&quot;
addDatEntry(&quot;s101&quot;
addDatEntry(&quot;s102&quot;
addDatEntry(&quot;s101&quot;
}

void addDatEntry(char* param)
{
for(int i =0; i<15; i++)
{
if(strcmp(sx.code,&quot;&quot == 0)
{
strcpy(sx.code, param);
sx.freq = 1;
break;
}
else
{
if(strncmp(sx.code, param,4) == 0)
{
sx.freq++;
break;
}
}
}
}
This shoud work..

Thanks,

Rating is not important, but it helps..
