If you want, you could code you own 'bitset' function for C. Basically, bitset<x>(d) outputs 'd' into binary, showing 'x' bits (so if you output bitset<10>(5), it outputs 0000000101). Though the problem with that is it only converts to binary. Good job though. |

Two possible improvements: 1) Eliminate the use of the `pow' function, which isn't needed. 2) Write a version which works for all integers n that can be represented as C ints. Currently this program only works for small nonnegative integers. |

a better one would be Quote: #include <stdio.h> int main() { int n; printf("Please input the integer you want to convert to binary:"); scanf("%d", &n); int i; for(i=0; i<bits; i++) { printf("%d", n<0); n <<= 1; } printf("\n"); return 0; } |
