now my program able to read the file by adding some code given by you, but i couldnt understand how it actually run..

#include <stdio.h><br /> <br /> <br /> void main (void)<br /> {<br /> char matrix[20][200], line[100][100];<br /> int i, j, x, no[20], quiz_1[20], quiz_2[20], quiz_3[20], project[20], midT[20], final[20];<br /> FILE *infile;<br /> <br /> infile = fopen("studentsmark.txt","r");<br /> <br /> x=0;<br /> while (fgets(line,100,infile)!=NULL)<br /> {<br /> <br /> x++;<br /> if(x==1)<br /> {<br /> <br /> }<br /> <br /> else{<br /> i=0;<br /> while( fscanf(infile,"%d %s %d %d %d %d %d %d",&#038;no<i>,matrix</i><i>, &#038;quiz_1</i><i>, &#038;quiz_2</i><i>, &#038;quiz_3</i><i>, &#038;project</i><i>, &#038;midT</i><i>, &#038;final</i><i>) !=EOF)<br /> <br /> <br /> <br /> printf("%d %s %d %d %d %d %d %dn",no</i><i>, matrix</i><i>, quiz_1</i><i>, quiz_2</i><i>, quiz_3</i><i>, project</i><i>, midT</i><i>, final</i><i>);<br /> i++;<br /> <br /> <br /> <br /> <br /> }<br /> <br /> }<br /> fclose(infile);<br /> }</i>

this is my actual input file

but i am unable to read tis line
No Matrix quiz1(5%) quiz1(5%) quiz1(5%) Proj(25%) MidT(20%)

what should i add to make the program read it and ignore it so it can read on the real data i need, i really have no idea…
