切换到头文件/实现/主文件后的C ++分段错误

Question

我得到了一个＆＃34;分段错误（核心转储）＆＃34;运行时错误，代码如下： 它在一个.pp文件中运行良好，但是当我将它分成标题/实现/主文件时，它会编译，但我得到分段错误错误。 更新*

主

#include <cctype>
#include <iostream>
#include <stdlib.h>

using namespace std;

#include "./mult_div.h"

int main(int arg, char *argv[] ){
    int diff=1;
    while(diff==1){

    bool check=1;
    char *argv2[1];
    char *argv3[1];
    argv2[0]=argv[1];
    argv3[0]=argv[2];
    cout<< argv2[0] << argv3[0]<<endl <<endl;
    while(check){
            cout<<"call bool"<<endl;
            if(is_valid_dimensions(*argv2, *argv3)){
                    check = false;
    }
            else
                    check=true;
    }


    cout<<*argv2[0]<<" "<<*argv3[0]<<endl;

    int rows= atoi(argv[1]);
    int cols= atoi(argv[2]);

    cout<< rows <<" " <<  cols<< endl;

    mult_div_values **table;
    table = create_table(rows, cols);
    set_mult_values(table, rows, cols);
    set_div_values(table, rows, cols);

    print_mult_table(table, rows, cols);

    print_div_table(table, rows, cols);

    delete_table(table, rows, cols);
    cout<<"Would you like to see a different size matrix(0-no, 1-yes)?" << " ";
    cin>>diff;
    if(diff == 1){
    cout<<"Enter a new size matrix:"<<endl;
    cin>> argv[1] >> argv[2];
    }

    }

实施

mult_div_values **table = new mult_div_values *[m];
for( int i=0; i<m; i++){
        table[i] = new mult_div_values [n];
}
return table;
}

                table[i-1][j-1].mult = i*j;
        }
}
}
void set_div_values(mult_div_values **table, int m, int n){
for(int i=1; i<=m; i++){
        for(int j=1; j<=n; j++){
                table[i-1][j-1].div =(float) i/(float) j;
        }
}
}
void print_mult_table(mult_div_values **table, int m,int n){

                    cout << table[i][j].mult << " ";
            }
            cout << endl;
    }
}


void print_div_table(mult_div_values **table, int m, int n){

               cout<< table[i][j].div << " ";
        }
        cout << endl;
}}

void delete_table(mult_div_values **table, int m, int n){

        delete[] table[i];
}
delete[] table;}}
