Hi, the following program prompts the user to enter a few lines of string and a character as a search key and outputs the total number of times that character appeared in those lines entered. However the bug is that the program prints "Enter string" twice and then i can't enter the first string. How come?
thnx in advance
Code:
/* character occurence count */
#include <stdio.h>
#include <string.h>
int main()
{
int occurrenceCount = 0;
char *searchPtr;
char string[ 400 ];
char tempStr[ 150 ];
int numLines;
int i;
char key;
printf( "Number of lines to be inputted: " );
scanf( "%d", &numLines );
for ( i = 0; i < numLines; i++ ) {
printf( "Enter string: " );
gets( tempStr );
strcat( string, tempStr );
}
printf( "Enter search character: " );
scanf( "%c", &key );
searchPtr = strchr( string, key );
while ( searchPtr != NULL ) {
++occurrenceCount;
searchPtr = strchr( searchPtr + 1, key );
}
printf( "\n\nTotal of occurrence character \'%c\' appeared in line(s) entered: %d\n\n",
key, occurrenceCount );
system( "PAUSE" );
return 0;
}
