Use C programe: Add the code in the function int stringCombine which adds the string stored in src to the end of dest. The header file string.h CANNOT be included. Assume that the length of the combined string is below 256. The main function is as follows: # include <stdio.h> void stringCombine(char* dest, char* src); int main() { char str1[100], str2[256]; gets(str1); gets(str2); stringCombine(str2, str1); puts(str2); return 0; } void stringCombine(char *dest, char *src){ //Your code here. } example: abc\n def print out abcdef

Here is the code for the function int stringCombine:
```
void stringCombine(char *dest, char *src) {
int dest_len = 0;
while (dest[dest_len] != '\0') {
dest_len++;
}
int i = 0;
while (src[i] != '\0') {
dest[dest_len + i] = src[i];
i++;
}
dest[dest_len + i] = '\0';
}
```
This function first finds the length of the destination string by iterating through it until it finds the null terminator ('\0'). Then, it copies each character from the source string to the end of the destination string, and adds a null terminator at the end of the combined string. Note that this implementation assumes that the source string is null-terminated.

Here is the code for the function `stringCombine`:
```
void stringCombine(char *dest, char *src) {
int dest_len = 0;
while (*dest != '\0') {
dest++;
dest_len++;
}
while (*src != '\0') {
*dest = *src;
src++;
dest++;
dest_len++;
}
*dest = '\0';
}
```
This function first finds the length of the destination string by iterating through it until it finds the null terminator (`'\0'`). Then, it copies each character from the source string to the end of the destination string, and adds a null terminator at the end of the combined string. Note that this implementation assumes that the source string is null-terminated.
In this implementation, pointer arithmetic is used instead of array indexing to access the characters in the strings. This is a common practice in C programming.
programe for solution of reissner's plate bengding problemes by the boundary
Reissner板弯曲问题的边界求解方法可以通过以下程序实现:
1. 定义问题:首先,我们需要定义Reissner板的几何形状和边界条件。通过确定板的长度、宽度和厚度,以及边界处的支撑或约束条件,我们可以建立问题的几何模型。
2. 网格划分:将Reissner板划分为一系列离散的小元素,如三角形或四边形。这些小元素可以通过有限元方法进行建模,其中每个元素的形状函数用于描绘变形的形状,并且板的位移和应力场可以通过对这些形状函数进行加权来表示。
3. 位移场和应变场的计算:对于每个小元素,通过解析或数值方法计算其位移场和应变场。位移场可以通过解Reissner板的小变形方程来计算,而应变场则是位移场的导数。
4. 应力场的计算:通过Reissner板的弹性本构关系,可以根据已知的应变场计算出相应的应力场。这可以使用Hooke定律和应变-应力关系来完成。
5. 边界条件的施加:根据Reissner板的边界条件,在边界上施加得到的位移或应力的约束。这可以通过在边界上引入适当的修正项或导入边界积分方法来实现。
6. 解方程:将所有小元素的位移、应变和应力场组装成整个Reissner板的位移矢量、应变矢量和应力矢量。然后,通过求解整个板的位移和应力方程组,可以得到Reissner板的解。
7. 结果分析:对于给定的几何和边界条件,我们可以计算出Reissner板的位移、应变和应力分布。这些结果可以用来评估板材在不同载荷和边界条件下的弯曲性能,以及确定板材在工程应用中的可靠性。
综上所述,通过以上步骤,我们可以编写一个程序来求解Reissner板的边界弯曲问题,以获得该板材的位移、应变和应力分布。这样的程序可以在工程实践中用于设计和分析各种结构中使用的Reissner板的性能。
