c语言字符串拼接的有哪些方法
在C语言中,字符串拼接有多种方法,以下是其中几种经常使用的方法:
char *strcat(char *dest, const char *src);
示例:
#include <stdio.h>
#include <string.h>
int main() {
    char str1[50] = "Hello";
    char str2[] = " World!";
    
    strcat(str1, str2);
    
    printf("%s
", str1);
    
    return 0;
}
输出结果为:Hello World!
int sprintf(char *str, const char *format, ...);
示例:
#include <stdio.h>
int main() {
    char str[100];
    char name[] = "Alice";
    int age = 20;
    
    sprintf(str, "My name is %s and I am %d years old.", name, age);
    
    printf("%s
", str);
    
    return 0;
}
输出结果为:My name is Alice and I am 20 years old.
#include <stdio.h>
int main() {
    char str1[50] = "Hello";
    char str2[] = " World!";
    int i = 0, j = 0;
    
    while (str1[i] != '
