1. 基本方法是定义一个函数 `deleteChar`，该函数需要两个参数：字符串 `str` 和要删除的字符 `c`。通过遍历字符串中的每个字符，当遇到与 `c` 相匹配的字符时，执行删除操作。以下是该方法的实现代码：```c void deleteChar(char *str, char c) { char *ptr = str;while (*ptr != '\...
To remove the first character of a string, we can use the char *str = str + 1 in C. it means the string starts from the index position 1. Here is an example: #include <stdio.h> #include <string.h> int main() { char name[6] = "vamsi"; char *result = name+1; printf("%s...

h> int main() { remove("D:/File/dst.avi"); return 0; } 执行前 : 执行后 : 二、rename 函数重命名文件 rename 函数原型 : 将文件由 char *oldname 重命名为 char *newname ; 代码语言:javascript 复制 #include <stdio.h> int rename(char *oldname, char *newname); char *oldname 参数是...
char *new_str = remove_substring(str, substr); printf("Original string: %s ", str); printf("New string: %s ", new_str); free(new_str); return 0; } 运行上述代码,输出结果为: Original string: hello world, this is a test New string: hello world, this a test ...
int remove(const char *filename)参数filename -- 这是 C 字符串,包含了要被删除的文件名称。返回值如果成功,则返回零。如果错误,则返回 -1,并设置 errno。实例下面的实例演示了 remove() 函数的用法。#include <stdio.h> #include <string.h> int main () { int ret; FILE *fp; char filename[] ...
