        int j=0,k=0,l=0,p=0,occ_of_plus,occ_of_equal,occ_of_m;
        for(int i=0;str[i]!='+';i++)//finding occurence of + in the string
        {
            s1[j]=str[i];
            j++;
        }
        s1[j]='\0';
        
        j++;
        for(int i=j;str[i]!='=';i++)//finding occurence of '=' in string

            k++;
            p=i;
        }

        k++;
        for(int i=p+2;i<str.size();i++)
        {

            l++;
        }
        s3[l]='\0';
        l++;
