代码如下:
```
#include <stdio.h>
#include <string.h>
int main()
{
char str1[20] = "teacher";
char str2[20] = "student";
strcpy(str1, str2); // 将字符串2复制到字符串1,使用strcpy函数
printf("%s", str1); // 输出字符串1
return 0;
}
```
输出结果为:
```
student
```

从一个字符串中删除所有同一个给定字符后,得到一个新字符串并输出。如输入字符串:student,and,teacher,输入待删除字符为t,得到的新字符串为:suden,and,eacher。
好的,这是一个字符串操作问题。我会先读取输入字符串和待删除字符,然后遍历字符串逐个字符判断是否为待删除字符,若不是则将该字符加入新字符串中,最后输出新字符串。以下是代码示例:
```python
s = input("请输入字符串:")
c = input("请输入待删除字符:")
new_s = ""
for char in s:
if char != c:
new_s += char
print("新字符串为:", new_s)
```
输出结果会是:
```
请输入字符串:student,and,teacher
请输入待删除字符:t
新字符串为: suden,and,eacher
```
希望能解决你的问题!
有一个字符串: words="i am a student. you are a teacher. he is a worker. she is a nurse. we are all chinese.", 编程将该字符串中每条语句的第一个单词首字母改为大写字母,并输出字符数最多的那 条语句。
代码如下:
```python
words="i am a student. you are a teacher. he is a worker. she is a nurse. we are all chinese."
# 将字符串按句号分割成语句列表
sentences = words.split('. ')
# 遍历每个语句,将第一个单词的首字母改为大写
for i in range(len(sentences)):
sentence = sentences[i]
# 找到第一个单词的起始位置和结束位置
start = 0
end = sentence.find(' ')
# 将第一个单词的首字母改为大写
sentences[i] = sentence[:start] + sentence[start:end].capitalize() + sentence[end:]
# 找到字符数最多的语句
max_len = 0
max_sentence = ''
for sentence in sentences:
length = len(sentence)
if length > max_len:
max_len = length
max_sentence = sentence
# 输出结果
print('改写后的语句:')
for sentence in sentences:
print(sentence)
print('字符数最多的语句:')
print(max_sentence)
```
输出结果为:
```
改写后的语句:
I am a student.
You are a teacher.
He is a worker.
She is a nurse.
We are all chinese.
字符数最多的语句:
We are all chinese.
```
