如何将类似Printf的格式字符串与argv一起使用

你可以这样做。该解决方案在字符串大小检查方面还有很多需要改进的地方,但其基础就是这一点。

输入要处理的批处理中的路径、文件编号基数和文件数量。

#include <stdio.h>

int main (int argc, char *argv[])
{
    unsigned basenum, numfiles, i;
    char inname[1000], outname[1000];

    if (argc < 5)
        return 1;
    sscanf(argv[3], "%u", &basenum);
    sscanf(argv[4], "%u", &numfiles);
    for (i=0; i<numfiles; i++) {
        sprintf (inname, "%s/%03u.png", argv[1], basenum + i);
        sprintf (outname, "%s/%03u.blah", argv[2], basenum + i);
        //convertimg (inname, outname);
        printf ("Processed %s to %s\n", inname, outname);
    }
return 0;
}

程序输入

test aaa dest/bbbb 100 10

程序输出

Processed aaa/100.png to dest/bbbb/100.blah
Processed aaa/101.png to dest/bbbb/101.blah
Processed aaa/102.png to dest/bbbb/102.blah
Processed aaa/103.png to dest/bbbb/103.blah
Processed aaa/104.png to dest/bbbb/104.blah
Processed aaa/105.png to dest/bbbb/105.blah
Processed aaa/106.png to dest/bbbb/106.blah
Processed aaa/107.png to dest/bbbb/107.blah
Processed aaa/108.png to dest/bbbb/108.blah
Processed aaa/109.png to dest/bbbb/109.blah
