; char target = 'o'; int index = findCharIndex(str, target); if (index != -1) { printf("The index of '%c' in the string is %d\n", target, index); } else { printf("The character '%c' was not found in the string\n", target); } return 0; } 在上述示例中,我们定义...

#include<stdio.h>#include<string.h>intmain(){charstr[]="hello world";char*ptr;ptr=strrchr(str,'o');if(ptr!=NULL){printf("Found at position: %ld\n",ptr-str);}else{printf("Not found\n");}return0;} 结果: Found at position:7 代码分析: 这段C代码首先定义了一个字符数组 str 包含...

nIndex是第一个被删除的字符,nCount是一次删除几个字符。根据我实验得出的结果:当nCount>要删除字符串的最大长度(GetCount() -nIndex)时会出错,当nCount过大,没有足够的字符删除时,此函数不执行。 例子 CString str1,str2,str3; char a; str1 = "nihao"; ...
