代码如下

#include<stdio.h>
#include<string.h>

int main(int argc, char const *argv[])
{
    char buf[128] = {0};
    int m1 = 0, m2 = 0;
    int s1 = 0, s2 = 0;
    char lrc[128] = "";
    sscanf("[02:16.33][04:11.44]我想大声宣布对你恋恋不舍","[%*1d%d",&m1);
    sscanf("[02:16.33][04:11.44]我想大声宣布对你恋恋不舍","[%*d%*[^4]%d",&m2);
    sscanf("[02:16.33][04:11.44]我想大声宣布对你恋恋不舍","%*[^:]%*c%2d",&s1);
    sscanf("[02:16.33][04:11.44]我想大声宣布对你恋恋不舍","%*[^:]%*c%*[^:]%*c%2d",&s2);
    sscanf("[02:16.33][04:11.44]我想大声宣布对你恋恋不舍","%*20s%s",lrc);    
    printf("%d秒打印歌词%s\n",m1*60+s1,lrc);
    printf("%d秒打印歌词%s\n",m2*60+s2,lrc);
    return 0;
}

运行结果如下
