1、將一個字符串逆序 2、將一個鏈表逆序 3、計算一個字節(jié)里（byte）里面有多少bit被置1 4、搜索給定的字節(jié)(byte) 5、在一個字符串中找到可能的最長的子字符串 6、字符串轉(zhuǎn)換為整數(shù) 7、整數(shù)轉(zhuǎn)換為字符串 1、char *strconv(char *p) { int i,length; char temp; length = strlen(p); for(i = 0;i < length/2;i++) { temp = *(p + i); *(p + i) = *(p + length - 1 - i); *(p +length - 1 - i) = temp; } return p; } int main() { char src[100]; char *p; scanf("%s",src); p = strconv(src); printf("%s\n",p); return 0; } 3、int cal(int data) //calculation the number of bit in one byte { int a; int count = 0; a = data % 100; while (a != 0) { count += a % 2; a /= 2; } return count; } int main() { int d,count; scanf("%d",&d); count = cal(d); printf("%d of one\n",count); return 0; } 4、#include #include void findmax(char *p) { int j = 0,max = 0; int count = 0; char record[200]; char recordmax[200]; for(int i = 0;;i++) { if((*(p + i) == ' ') || (*(p + i) == '\0')) { if(count > max) { max = count; record[j] = '\0'; strcpy(recordmax,record); } count = 0; j = 0; } else { record[j] = *(p + i); count ++; j ++; } if(*(p + i) == '\0') break; } printf("%s\n",recordmax); } int main() { char str[]="zeng weidsfdsaf langd hah"; printf("%s\n",str); findmax(str); return 0; } |
