Program run perfectly without error but cant show anything

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

  1. The problem statement, all variables and given/known data:

No problem,but it cannot show what I want

  1. Relevant commands, code, scripts, algorithms:
    wc test.cpp
    wc test.cpp | ./test -l

  2. The attempts at a solution (include all code and scripts):

#include <iostream>
#include <cstdlib>
#include <cstring>
using namespace std;

int main (int argc, char *argv[])
{
    string str;
    char *str1 = new char[80];
    int SUM=0,count=0;
    string fsize;
    int min=0,max=0;

    getline (cin, str);
    strcpy (str1, str.c_str());
    fsize = strtok (str1," ");
    if(argc==1){
            cout<<"Not enough arguements!";

    }

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

                if(strcmp(str1,"-b")==1){

                    for (int m=0; m<=2; m++)
                        fsize = strtok (NULL, " ");
                    if (atoi(fsize.c_str()) > max) {
                        max = atoi(fsize.c_str());
                        SUM=SUM+max;}
                    if (atoi(fsize.c_str()) < max) {
                        min = atoi(fsize.c_str());
                        SUM=SUM+max;}
                    count++;}
                else if (strcmp(argv,"-l")==1){

                    for (int m=0; m<=2; m++)
                        fsize = strtok (NULL, " ");
                    if (atoi(fsize.c_str()) > max) {
                        max = atoi(fsize.c_str());
                        SUM=SUM+max;}
                    if (atoi(fsize.c_str()) < max) {
                        min = atoi(fsize.c_str());
                        SUM=SUM+max;}
                    count++;}
                else if (strcmp(argv,"-w")==1){

                    for (int m=0; m<=2; m++)
                        fsize = strtok (NULL, " ");
                    if (atoi(fsize.c_str()) > max) {
                        max = atoi(fsize.c_str());
                        SUM=SUM+max;}
                    if (atoi(fsize.c_str()) < max) {
                        min = atoi(fsize.c_str());
                        SUM=SUM+max;}
                    count++;}
                else
                    cout<<"\nInvalid Input!\n";

                cout << "There are " << count << " files" << endl;
                cout << "Largest file has " << max << " bytes" << endl;
                cout << "Smallest file has " << min << " bytes" << endl;
                cout << "The ToTal is " << SUM  << endl;
	}
	return 0;

}

This is my program,what I want is do this program to check how many bytes,lines and words inside any of the file.
When I type wc test.cpp it will pop out
6 111 12608 test
But when I type wc test.cpp | ./test -l
it give me segmentation fault(core dumped)
Anyone can help me with this?
