Question

programming in c

convert binary representation of a number to an unsigned integer.

T,t=1, F,f=0

other characters are ignored

STOP converting when a space appear or at the end of the string.

for example ftft or FTFT =5, bTFdt TT=5

unsigned int 123(const char *binary)

{

}

If you have any doubts, please give me comment...

#include<stdio.h>

#include<math.h>

unsigned int c123(const char *binary)

{

int i=0, len = 0;

while(binary[i]!='' && binary[i]!=' '){

if(binary[i]=='T' || binary[i]=='t' || binary[i]=='f' || binary[i]=='F')

len++;

i++;

}

int num = 0;

i=0;

while(len>0){

if(binary[i]=='T' || binary[i]=='t' || binary[i]=='f' || binary[i]=='F'){

num += (binary[i]=='T' || binary[i]=='t')?pow(2, len-1):0;

len--;

}

i++;

}

return num;

}

int main(){

printf("ftft: %d ", c123("ftft"));

printf("FTFT: %d ", c123("FTFT"));

printf("bTFdt TT: %d ", c123("bTFdt TT"));

}
