I have trouble with C programming converting from decimal to binary?

Hello, I am taking a programming class and I wrote the following program for C. I was unable to use the power function in the math library so I made my own, but it only works for converting from 0 to 1023, when I try 1024 the answer is wrong. I think it has something to do with the fact that 1024 requires 10 bits, but I dont know how that fits into the program's bug. thanks


#include %26lt;stdio.h%26gt;


#include %26lt;math.h%26gt;





int power (int , int);





main()


{


int deci, resid, binary, count, multiplier;





printf("input a number: ");


scanf("%d", %26amp; deci);





count=0;


binary=0;





if (deci%26gt;0)


{


while (deci%26gt;0)


{


resid=deci%2;


multiplier = (power (10, count));


binary=(resid*multiplier)+binary;


deci=deci/2;


count=count+1;


}


}


printf("0b%d\n", binary);


}


int power(int base, int exp)


{


int ans;


ans=1;


if (exp==0)


{


return ans;


}


else


{


while (exp%26gt;=1)


{


ans=base*ans;


exp=exp-1;


}


return ans;


}


}

I have trouble with C programming converting from decimal to binary?
.. I dont have a c complier any more so bear with me .. I'm doing this in my head.. But you are trying to take a binary number and you are representing it in a decimal form





meaning your answer may be "1001" = 9


but the var you are storing it into is seing 1001 = 1001


you are simply running out of space.. Convert your answer to char thus the answer = "1001\0" readable





hope this works


and I didnt run you out to the wrong conculision
