Passing arguments from command line to switch case statement in C
Hi
Am pretty new to C..
Am trying to pass the arguments from command line and use them in switch case statement..
i have tried the following
Code:
#include <stdlib.h>
main(int argc, char* argv[])
{
int num=0;
if ( argc == 2 )
num = argv[1];
printf("%d is the num value",num);
switch ( num )
        {
            case 1:            /* Note the colon, not a semicolon */
             printf("Playing the game\n");
             break;
            case 2:
                printf("Loading the game\n");
                break;
            default:
                printf("The value is not correct\n");
                break;
}
}

I get the output as
Code:
# ./wq 1
804400053 is the num valueThe value is not correct

Please help..

frexp

frexp(3M)						  Mathematical Library Functions						 frexp(3M)

NAME

       frexp, frexpf, frexpl - extract mantissa and exponent from a floating-point number

SYNOPSIS

       c99 [ flag... ] file... -lm [ library... ]
       #include <math.h>

       double frexp(double num, int *exp);

       float frexpf(float num, int *exp);

       long double frexpl(long double num, int *exp);

DESCRIPTION

       These functions break a floating-point number into a normalized fraction and an integral power of 2. They store the integer exponent in the
       int object pointed to by exp.

RETURN VALUES

       For finite arguments, these functions return the value x, such that x is a double with magnitude in the interval [1/2, 1)  or  0,  and  num
       equals x times 2 raised to the power *exp.

       If num is NaN, NaN is returned and the value of *exp is unspecified.

       If num is +- 0, +- 0 is returned and the value of *exp is 0.

       If num is +-Inf, num is returned and the value of *exp is unspecified.
