Ｃ语言使用位移转换二进制

#includeint convertIntToBinary(int src, unsigned char *arr){ //unsigned char arr[32]; int i; for(i=0;i<32 i="" if="" src="=0)" break="" arr="" i="" src="" 0x00000001="" src="src">>1; } return i;}int main(){ unsigned char arr[32]={'\0'}; int src = 777; int ret=convertIntToBinary(src, arr); for(int i=0;i<ret;i++){ printf("%d", arr[i]); } return 0;}
