c语言中如何让输出的数值分段
进行数值分段主要进行字符串分割，使用strtok函数即可实现字符串分割。这里引用一段strtok用法：
The strtok() function returns a pointer to the next "token" in str1, where str2 contains the delimiters that determine the token. strtok() returns NULL if no token is found. In order to convert a string to tokens, the first call to strtok() should have str1 point to the string to be tokenized. All calls after this should have str1 be NULL.
For example:char str[] = "now # is the time for all # good men to come to the # aid of their country";
char delims[] = "#";
char *result = NULL;
result = strtok( str, delims );
while( result != NULL ) {undefined
printf( "result is \"%s\"\n", result );
result = strtok( NULL, delims );
}
/* 何问起 hovertree.com */
The above code will display the following output:
result is "now "
result is " is the time for all "
result is " good men to come to the "
result is " aid of their country"

c语言拆分数运算
从键盘上输入一个4位数的整数n，编写程序将其拆分为两个2位数的整数a和b，计算并输出拆分后的两个数的加、减、乘、除和求余运算的结果。例如n=-4321,设拆分后的两个整数为a,b，则a=-43,b=-21。除法运算结果要求精确到小数点后2位,数据类型为float。求余和除法运算需要考虑除数为0的情况，即如果拆分后b=0,则输出提示信息"The second operater is zero!"
输入提示信息："Please input n:\n"
输入格式: "%d"
输出格式：
拆分后的两个整数的输出格式："%d,%d\n"
加法、减法、乘法的输出格式："sum=%d,sub=%d,multi=%d\n"
除法和求余的输出格式："dev=%.2f,mod=%d\n"
除数为0的提示信息："The second operator is zero!\n"
#include stdio.h
int main(void)
{
int input_number,separate_number_a,separate_number_b;
printf("Please input (4 digit) Number n:\n");
scanf("%d",input_number);
separate_number_b = input_number % 100;
separate_number_a = input_number / 100;
printf("The separate number are:%d,%d\n",separate_number_a,separate_number_b);
printf("sum=%d,sub=%d,multi=%d\n",separate_number_a+separate_number_b,separate_number_a-separate_number_b,separate_number_a*separate_number_b);
if(separate_number_b == 0)
printf("The second operator is zero!\n");
else
printf("dev=%.2f,mod=%d\n",(float)separate_number_a/separate_number_b,separate_number_a%separate_number_b);
return 0;
}
c语言如何拆分数字
小弟有这么一种做法，我觉得这个比较快一点。写得不是很好，你看下先啦！
#includestdio.h
#includestring.h
#includewindows.h
int main()
{
char a[30];
int i,l;
printf("请输入一整型数字：");
gets(a);
printf("数字拆分如下：\n");
l=strlen(a);
for(i=0;il;i++)
printf("%d ",a[i]-'0');//将数字字符转为数字值
printf("\n");
}
你看一下，还可以的话，麻烦你采纳我,Thank you。
