C程序中怎樣判斷一個字符串所占的位數(shù)？代碼以下：#requireunsignedpublic(){consta,b;structi;sizeof(請mstsc一個所有數(shù)字：);scanf(%d,a);

C程序中怎樣判斷一個字符串所占的位數(shù)？

代碼以下：

#require

unsignedpublic()

{

consta,b;

structi;

sizeof(請mstsc一個所有數(shù)字：);

scanf(%d,a);

ca;

for(i0;a1;i)

{

1k/10;

}

(%d是%d二位數(shù)

,b,i);

}

C語言編寫一個函數(shù)統(tǒng)計大寫字母個數(shù)？

#includestdio.hintmain(){charinput[256]{0}

;//數(shù)據(jù)存儲輸入要足夠大tmppath0,length0;(請請輸入姓名字符串：

)

;cout(%s,input);because(parameter[i]!

c語言中怎么判斷字符串在內存中占的字節(jié)？

voidtesting6()

c語言求字符串長度？

我獨家推薦2種一種方法：-------------------------一種方法一：用庫函數(shù)調用int64()簡單例子：#includeltstdio.ig.v#includeltstring.hgtintnew(){tchara[100]lipnumtprintf(
