if(choice=='y'||choice=='a') //main() change your second option ..y=a. then try it . |

i forgot~~i wanted to say,i made a project in wxDEV_C++,and copyed the code in it,the wxDEV_C++ told me could not compile successfully;then i thought something was wrong in
"if(choice=='y'||choice=='a') main();", as far as i concerned, the "main()" can not use again in one programme, |

At last i find a new solution solve my problem which i proposed yesterday,using the "goto";code is as follows:
Code:
#include<stdio.h>
float add(float,float);
float sub(float,float);
float product(float,float);
float divide(float,float);
int main(int argc, char *argv[])
{
float n1,n2;
char sym,choice;
printf("This Program is a program for calculator\n\n");
start_again:
scanf("%f%c%f",&n1,&sym,&n2);
if(sym=='+')
printf("\n%f",add(n1,n2));
if(sym=='-')
printf("\n%f",sub(n1,n2));
if(sym=='*')
printf("\n%f",product(n1,n2));
if(sym=='/')
printf("%f",divide(n1,n2));
printf("\nDo you wish to continue[y/n]");
scanf("%s",&choice);
if(choice=='y'||choice=='Y')
goto start_again;
system("PAUSE");
return 0;
}
float add(float m1,float m2)
{ return(m1+m2);}
float sub(float m1,float m2)
{ return(m1-m2);}
float product(float m1,float m2)
{ return(m1*m2);}
float divide(float m1,float m2)
{ return(m1/m2);}

i add some functioins and program a new code that based on codezone as follows:
Code:
#include<stdio.h>
float add(float,float);
float sub(float,float);
float product(float,float);
float divide(float,float);
int main(int argc, char *argv[])
{
float n1,n2;
char sym,choice;
printf("This Program is a program for calculator\n");
printf("Please input two numbers like this:4+5 or 4*5\n");
start_again:
scanf("%f%c%f",&n1,&sym,&n2);
if(sym=='+')
printf("\n%f",add(n1,n2));
if(sym=='-')
printf("\n%f",sub(n1,n2));
if(sym=='*')
printf("\n%f",product(n1,n2));
if(sym=='/')
printf("%f",divide(n1,n2));
printf("\nDo you wish to continue[y/n]\n");
input:
scanf("%s",&choice);
if(choice=='n'||choice=='N')
{
printf("Good Luck!!ByeBye!~\n");
goto end;
}
else if(choice=='y'||choice=='Y')
{
printf("Please Contiue:\n");
goto start_again;
}
else if(choice!='n'||choice!='N'||choice!='y'||choice!='Y')
{
printf("Wrong code!\n");
printf("Input again:\n");
goto input;
}
end:
system("PAUSE");
return 0;
}
float add(float m1,float m2)
{ return(m1+m2);}
float sub(float m1,float m2)
{ return(m1-m2);}
float product(float m1,float m2)
{ return(m1*m2);}
float divide(float m1,float m2)
{ return(m1/m2);}

Okay, I understand its meant to be a bare bones sort of program, but still you should include a check for division by 0.
